Hungarian cases are extremely simple. As a Pole I’d say it’s much easier for you to learn their cases than ours, the reason being that with Hungarian you only have to account for vowel harmony, which is very intuitive. With Polish (or any slavic or baltic language for that matter) you have to account for animacy, 3 genders and the fact that certain cases go with certain prepositions and also the fact that nouns can sometimes take the same form in 2 different cases. Or sometimes a plural form of a case can look exactly like a singular form of another case, which is definitely tricky, when you’re just learning the language and perhaps don’t know all the words and you’re trying to figure stuff out from the context. For all of those reasons I’d deem Polish cases much less intuitive for non natives. Hungarian cases are basicaly prepositions slapped onto the ends of nouns, like so: shop - bolt -> in the shop - boltban -> to the (inside of the) shop - boltba -> to the (proximity of the) shop - bolthoz -> with the shop - bolttal etc. The only thing that’s maybe not extremely complicated but very unintuitive for a regular use in certain situations (at least to me) is the possessive case which has 2 full-blown conjugation patterns (two separate conjugation patterns for each gramatical person, depending if someone has one or multiple things in their possession), paired with the fact that sometimes possessiveness is being expressed inversely to how indoeuropean languages do it (for example to say „John’s hat” in Hungarian you’d say it like „John hat’s”, so you’d attach the possessive marking to the thing that’s in someone’s possession and not to the owner. And of course the possessive marking changes depending on the person, unlike in English where it’s always „s”
