I find that wrapping the tips with nail polish and doing the same with top coat helps a lot. I like Seche Vite. You apply it while the polish is still wet. The Zoya top coat is good too.
Essie chips on me more than any brand probably. It seems to vary a lot for people though, might have something to do with body chemistry.
Also if you look up JessFace90’s channel on YouTube she has some nail care and painting videos (look for tips playlist if you don’t want to scroll through her uploads) that might help with the basics
