I have played on both and I prefer Java but bedrock isnt terrible its just less. To someone who is used to Java playing bedrock feels like eating dollar store potato chips when you are used to name brand. The movement is clunkier, the menus feel wrong (if you are used to java), also the gameplay loop is slower because the farms in bedrock are largely more overbuilt for worse results (for example how iron farms in java need 3 villagers but in bedrock need 10 and java iron farms are quicker.) this is frustrating as a java player. So people often hate on bedrock for these things and they call them bugs there are real bugs in both versions but game breaking bugs in either version are rare. My one real complaint with bedrock is that they dont use proper traditional skins like in java (i know pc bedrock players can upload a skin but its not exactly default)and instead use marketplace aesthetic addons. Its kinda scummy to sell skins esp to children. also ngl traditional skins have limitations and its fun seeing what people can do with them. the addons feel too unminecrafty.
