Okay, if you put it that way, it makes little difference whether you start fresh or not. Maybe you'll do better on a reroll. But in terms of waifus, Beidou's still my favorite, and you've got her, too.

You could certainly start anew, play to where you'd been, see how it goes, and then flip back if you don't like the results. I just checked, and the second batch of free wishes comes at Adventurer Rank 7. So maybe play to AR7 twice -- which shouldn't be too much of a time commitment -- and compare after.

(Note: the rewards at AR7 are primogems rather than wishes. You use gems to buy wishes, but there are two types. Make sure you're pulling on the character banner, aka the one with the pink, colorful wishes.)
