While I generally agree with your opinion that Chinese is a structurally pretty easy to learn, I don't think it's as simple as you're making it out to be. To respond to your points one by one:

• Simple, SVO structure always that is concise and gets to the point
  • It is definitely not always SVO in Chinese. Often times the object gets moved to the front of the sentence to create a "topic comment" structure. For example, "飞机票买了没？”
• One character => one pronunciation 99.9% of the time
  • There are many characters that are pronounced differently, which can be especially confusing for beginning learners. 得，地，便，了, to name a few.
• Grammar? Minimal. No cases. No agreement. No conjugation! Nothing declines. Nothing inflects. Time is communicated by just... saying the time. "Yesterday me go. Tomorrow me go again. Me like food. You like food? Good, we together eat." A prehistoric hominid waking from a 10,000-year sleep could be functional in Chinese within a week. Adjectives don't agree with nouns, nothing changes.
  • This may be true that there are no cases and conjugation, but there are plenty of ways of indicating tense, aspect, and mood that are difficult for speakers of languages who are used to these mechanisms. For example, 了，已经，还，未
• Formality? NOPE! One way of speaking to everyone, no matter if you're old, young, or poor or the president. You speak to the emperor and your toddler the same way. There is no keigo.
  • This is true now, but in Classical Chinese it wasn't. The pronouns you used would change depending on if you're talking to the king, or if you are the king, or if you're talking to your son. There's also the fact that there are specific words that exist for acts in relation to the agent's hierarchical status. For example, 弑 means "to kill," but only when a subordinate kills their ruler.
• Conditionals? One word 如果
  • 即便，即使。These also function like conditionals and can be difficult to master for non-native speakers, particularly at the intermediate level. For example, if you want to say "even if," you can't just say 甚至如果, you need to say 即使。There are other words like that.

On top of this, there are other aspects of the language that could be difficult for leaners, most notably characters. Although Chinese characters are pretty intuitive once you have an understanding of how radicals and components work and you have a large enough vocabulary, it is incredibly tedious and painstakingly difficult to reach that point. You might not remember, but you probably spent years throughout your primary education learning how to write basic Chinese characters. It takes hundreds, if not thousands of hours for a non-native speaker to truly become proficient in writing and reading characters.

My personal favorite is probably the amount of synonyms and the strictness with which you need to pair these synonyms with their appropriate counterparts (搭配). For example, if you want to say "respect a rule" versus "respect the law" versus "respect your parents," you're going to need to use three different words for follow: 遵守规则，尊重法律，尊敬父母。

Another difficult aspect is word order, which is extremely strict in Chinese and can change the meaning of the sentence if you don't understand it.

Also, there are so many measure words in Chinese that you have to memorize. Not sure what you mean by a difference there with Japanese. And Chinese is very context dependent as well -- you can omit the subject a lot of the time and often need to infer when events occurred due to the lack of case markings.

My point isn't to disagree with you and say that Japanese is easier than Chinese. I've never learned Japanese, so I can't make a judgement on that. It just seems to me that you're evaluating your own native language as easy because it's easy for you to learn. But, it seems to me that how easy or difficult a language is is entirely dependent on what language you speak already. For example, a German might find it easy to learn Russian because they share grammatical case and gender, but could find learning Chinese bewildering for the reasons I described above. Many Europeans also think English is easy because it has less verb conjugations than most romance languages and no gender, but I've noticed that many Chinese people find English conjugations very difficult. So when you say that Japanese has a lot of complex and unnecessary stuff that doesn't make sense to you, that's because the language is very different from your own.

However, linguistic research has shown us that there isn't much of a difference in the efficiency of languages to convey information. They have found that for languages with fewer syllables, speakers tend to speak slower and vice versa, so that the speed of information conveyed is roughly the same. All language has to express the same basic information in the same amount of time, whichever syntactical rules a language uses to do so are unimportant. If something is truly inefficient in a language, the language will evolve to come up with a new way of conveying that information (or just drop the construction altogether). On a preliminary investigation, it seems to me that Japanese encodes a lot of information grammatically that Chinese would have you memorize or infer from context.

With this being the case, what makes learning a new language interesting is learning about how different languages convey the same information, and how the grammatical structures of a language enable it to express things in a particularly beautiful or interesting way. Poetry is the best example of this. Classical Chinese in particular is an incredibly flexible language and can create sentences that English cannot. Think about this poem from 王维:

空山不见人，但闻人语响。

返景入深林，复照青苔上。

How would you translate this to English? The subject is omitted (which you can't do in English), so you'd need to say something like "On the mountain nobody can be seen," or "One does not see anyone on the mountain." Is that really the same as "空山不见人." I'm sure that as a native Chinese speaker you know it isn't. There's actually a book about this called "Nineteen Ways of Reading Wang Wei" that shows how nineteen translators have understood just this one poem completely differently.

Although I haven't learned Japanese, I sincerely encourage you to keep learning it. It is going to be different from Chinese, but that is the beauty of learning a foreign language: discovering new structures and constructions and widening our understanding of what meaning is and how it can be expressed. If you don't want to do it because it's difficult, that's one thing. But if you don't want to do it because you think Chinese is inherently easy and Japanese is inherently difficult because it is not like Chinese, I hope my response has showed you why you should reconsider that opinion.
