It does vary. Here are screenshots of one of my notes that got a lot of zaps for comparison in Primal, Nostur, and Nostrudel. I don’t have any others installed right now to check. Primal is very clean. Nostur is decent but displays them a bit more cluttered. NoStrudel defaults to showing reactions and you have to click into the note stats to even see the individual zaps at all, so not very useful for zapvertising.
