I used winrar , peazip and bandizip. But for some reason i liked Bandizip. I still don't know the reason. Maybe it's their website details and comparision
I used to use WinRAR but I switched over to 7-Zip and it works wonderful. The annoying nag screen on WinRAR used to annoy me (the thing that keeps coming up after the trial has ended, even though the program seems to be fully operational after it)
I used to always use WinRAR but I now use 7-Zip and haven't looked back.
