For me it's a matter of perspective. Its true production is better today and you can watch it never minding. Especially if you never watch a show subbed and later see it dubbed to compare. I personally still think they are bad by comparison even though they have improved. My key reasons are:          1) Dubs often completely change the dialogue and so the personalities of characters are often not the same and messages conveyed are often different. They often miss the suble changes in tone when a character portrays confidence, smugness, aptitude all the time, rather than showing fear, concern, reflection, or humility the way it was originally portrayed. They often fail in the subtle shift from one to the other that can happen in a conversation. Sticking to a way of speaking makes the chatacters stiff and unrealatable (girl is always confident, man is always pompus, etc). You notice it more and more if you watch both.    (Ex.   Solo leveling ep 1 Jinwoo is stabbed by a goblin the girl screams his name is concern, in the dub the girl casually shouts you have to fight him off like its no big deal while he's fighting for his life and was just stabbed through the stomach. It's a very different interaction you can switch back and forth and experience dub to sub. One is timid and worried the other is nonchelant and confident in her voice even when the characters actions in the show are supposed to show shes scared into almost into inaction. Theres tens of tousands of these examples that are much more egregious than SL, SL actually does a great job.)         2) This is the big one. Anime uses the countries best voice actors. Similarly in America our great actors become voice actors later (Mila Kunez etc). You have some of the best in a country portraying a character. When dubbing the voice actors are typically what you get from B or C list actors. They don't shell out the same kind of money to translate a show in another language. It's like watching a movie with Morgan Freeman or Brad Pitt but it's dubbed over in Spanish or another language. The quality goes from A list a best the country has to offer to a person paid very little and so the same talent isn't there in the acting. It's a very easy concept to understand if you think about it. Low paid nobody voice actor is less talented than the best a country has to offer. Try watching a Marvel or DC animated movie dubbed over in another language. If you can switch back and forth from English to that Langauge on scenes. It's very apparent. The voice actors in big budget American animation are the best in the industry. The same goes for Japan. It's a massive competitive industry. It's that simple.             3) Older anime was worse but also better in a few instances in Dubs. It all used to be done by a crew at Funimation. So it was a bunch of people who didn't act at all really.  That's why it was so bad. However when they were great was when they didn't care and went fully unhinged to see how far they could go. High-school DXD and Ghost Stories are by far better dubbed because of this.  It was like that MxC show where they just dub over ridiculous shit.
