>>11665472ck2 has more content ( if you own all DLC ) and especially mods. but ck3 runs much better. if you know eu4 you also know the lag. ck2 is worse than that.
ck3 runs super smooth even end game. and its easier to get into. i would say about hoi4 l recommend to get ck3. unless you really care about more content and have the money to buy every DLC.
