is it recording software or guitar software you are looking for? Recordingsoftware is like religion, Logic, cubase, Nuendo or PT, just find something and stick with it.

But I can´t tell you how suprised I am for Line 6´s Guitarport, it makes Guitar recording a dream, so easy to use, extremly cheap compared to what you get. I only use it in studio but there is no limit to what it can do. Ik Multimedia has made the Amplitube also very nice, but I prefere Guitarport anytime
