Playing all the FF pixel remastered games and wondering about the XP and Money boost they offer.

If I use the gold and exp boost will it ruin the games for me? I just don't have the time to grind unfortunately. So playing at like X2 boost for exp and gold seems great for me. But I'm guessing it will just kill any sort of difficulty right? I'm sure I'll be over leveled for most areas.... But even at max lvl will the end bosses and super bosses still be fun to play? Thank you for your time!
