I used to use Amlpitube 4, but now I just stick to Archetype Plini, Cory Wong, and Gojira. I have the Darkglass VST too for bass ;)

I think Plini is pretty good for modern tones. It has custom IRs too so there's a decent amount of sounds you can get through that as well. The three amps included are all essentially just different gain stages, but you do get an external overdrive and compressor in front of them. You get bass, middle and treble for each amp + and extra graphic eq so you definitely have a lot of options in that regard. 

Though IMO, it leaves a bit to be desired if you're into chunky, fuzzy lead tones (which I usually use Cory Wong for). Hope that helps :0
