In this debate for me, I am impartial because I have used both concrete physical amps and digital amps. Personally, each have there traits. You have the traditionalists who stick with tube amps and you have new artists like Tosin Abasi and Tim Henson using rack units like an Axe 8 or just programs. I have only used Amplitube and garage band for digital amps but I am getting an interface so I can record as well. I also have a little orange crush 20 for my amp. I feel like personally music, sound specifically will eventually have to revert back to tube amps because there's always a market for them. I think each digital and tube amps have their benefits and what ever benefits you and sounds good to you will treat you well. In this day and age, you don't need to drag your 4x12 and 100 watt head, you can get it all out of a computer. However, nothing will ever be as good as a real tube amp.
