The only stylus cleaner I’ve ever used is the Lyra stylus cleaner that came with my cartridge. I keep my records clean and use the stylus cleaner once every session, or so. I use a magnifier occasionally to check the cartridge. While I don’t have a basis for comparison, I have literally never felt the need to search for one. My eyes and, more importantly, my ears tell me it works just fine. (And since it comes from the manufacturer I have no worries about it harming the cartridge.)
