Best Characters To Play In Comp?

I haven’t touched comp in at least two years cause life got hectic and i took a break from it. But, I have been playing quick play often so i’m still familiar with the game. I want get back into comp and take it seriously, but my main problem is I haven’t bothered to learn to play the new characters in the past few years except Juno recently.

Last I remember, I placed gold in tank & dps and platinum in support. I have the most hours on Dva and Moira. I also play Sigma, Orisa, Soldier76, Torb, Luci, Mercy, Juno and Zen. Are any of them still good with the new meta and who is worth learning to rank up?

I also play on ps5 if that matters!
