my favourite is PowerArchiver (windows XP certified), full 7Z support,.. to quote a few features

i never used 7zip but im very happy with winrar and winrar got my vote

My vote for Winrar.

WinRAR is the easiest to use IMO. 7-zip gives better compression in most cases, but sometimes not! I made SFX installers using 7-zip and WinRAR for Photoshop, and the 7-zip installer came out 500kb larger...

Overall WinRAR.

I love freeware and IZArc does everything I need. Handles RAR, 7z, ACE plus every other format you can think of. Makes nice self-extractors too.

7zip offers the best compression, though WinRAR does have several features, but not free and PA is ok too, especially with its archive converter, but I found it was kinda buggy. 7zip gets my vote for being free and simple.

my vote goes to winrar, for reasons you can check my review

i love winrars features and i do se winrar, but 7z has better compression so thats what i picked

WinRAR is my favourite - been that way for decades - and the "demo" continues to work which is fine so really - WinRAR it is!

I've been using ZipGenius for a couple of years now.

Winrar. Been using since 3.20

Winrar for sure

I always use the Corp edition 3.50

i find 7z gives me the best compression most of the time, especially if you know how to use the parameters, but I voted winrar. It is the most well rounded, and gives pretty good compression overall. I use winrar for my everyday activities, which I can't say I do with 7z.

I generaly use 7-zip, but for the best compression I use WinUHA

It's a little slow but it compresses about 30% better than winzip.
