Returning player looking for realm suggestions.

I’ve done some poking around online to find server populations, but would like to get an opinion here as well. I’m looking to start a fresh vanilla (non-tbc/wotlk) character on Alliance.What would be the best realm to pick if I’d actually want to do leveling content? Which would be the best pvp realm and which the best pve?I played wow back during the original vanilla, as well as returned but never capped for classic. Nostalgia is calling me back again, but leveling is my favorite part about classic and I’m hoping to find as active of a server as possible.
