My above post applies as well, plus:
- I like Beidou's design and playstyle a lot, and she's pretty decent later on due to her counters, so I have her at level 80, no regrets.
- Yanfei is apparently very fun to play and a decent character, although I haven't levelled her up enough to have an opinion (and as I recently pulled Diluc, that's probably going to remain that way for a while).
- I've heard everything about Ningguang, from "decent" to "really good". I have no clue where her meta is right now.
One thing that's probably important to know is that over time you will get repeats, which turn into items that unlock further abilities for the character (up to six, these are called constellations). Some characters become much better with more constellations, and because of the RNG nature of wishes, you may have got a character right now that you will not get any more constellations for a while, whereas another character you don't have yet, the game may decide to grace you with a ton of constellations. This was what happened to me with Razor, which I got really late, but for some reason the game decided to shower me with after than, with the result that I have a 6 constellation monster that I never get around to level up because his role is more or less filled in my current party and I always have someone else more important to level up, hahah.
