OllyDbg is pretty fine (by me), but, i personally use SoftICE most of the time.

Quote from Fravia RCE FAQ :
"Is it better to use Softice or Ollydbg?
Even if Softice is more powerfull than Ollydbg, Ollydbg works well on most applications; the main difference is that Softice is kernel-mode and Ollydbg is user-mode... make your choice. "

From my expirience, there is much more 'anti protection' for SoftICE cuz it's more spread thru the crackers...

But, as advanced reverser, you should know how to use both of them, same as u use IDA and W32Dasm for disassembling ...

Hope this helps
