Amps are better all the way around. I had my simulator period but in the end, all my simulator tracks sounded like they were coming out of a plastic DI with bad or cloned fx which, once I thought about it, is exactly what they were.
For the price of of a VST instrument plugin you can pick up a Vox AC15C1, Used PrincetonRI , Used Deluxe ReverbRI and few pedals and have authentic sounding guitar tracks.
Getting off track on the ProChannel so I will steer the conversation back. A lot of people are complaining about the interface and not being able to see what frequency they are using in the graph. I think it's an advantage really because it forces you to use your ears, (remember those?), instead of relying on your eyes. That said, for a beginner, it is difficult to know what you're doing but for anyone that has done this awhile, it's actually a blessing in disguise which makes you focus on the sonics.
