For my money the best-in-class click and pop remover is Brain Davies’ excellent ClickRepair package. It costs a little at $40 but is well worth it IMHO if you have a lot of LPs to process. Brian does let you have a 21-day free trial so you can test out if it works for you. See this sticky thread: https://forum.audacityteam.org/t/click-pop-removal-clickrepair-software/1933/1
The other great thing is that Brian does not levy a maintenance charge - once you’ve bought the s/w you can get all future upgrades for free.
