I only know gloomspite so lemme tell ya. Gloomspite are a horde army so you will be painting well close to 60+ or 100+ miniatures. They’re all pretty simple designs though, so you don’t have to paint many different parts.
Squigs are always satisfying to see sprinting and bouncing across the entire table in the span of 1-2 turns.
Stabbas and shootas are meh, but it’s always fun for the other person to wipe out bunches of miniatures in a single attack. Also rolling 20+ dice is very satisfying.
Spiders are spiders. I don’t use them. Same with wolves. No particular reason, i just don’t own any.
Yeah I’m new too so here’s where I’ll stop.
