One more between osrs and rs3

hey everyone! i'm passionate about runescape, but I’ve been stuck in a limbo — osrs feels too old, and rs3's combat puts me off. I’ve tried multiple times but couldn’t get into it. Now I’m considering playing as an ironman in legacy mode, because it combines the newer game with a combat style I like, plus it adds a challenge that keeps me motivated.

would I be missing out on a lot by playing this way?
