I've been going Variax to Wampler Super-plextortion to POD HD (first it was an XTLive) to H2O chorus\echo to Valve Jr (and now a VHT Special 6) for a long time. And I really like the tones I get from most of it. You really need to try it yourself. There are a lot of preconceived notions as to what modelers should and should not do. I don't care for FRFR and the way I do it gives me an amp in the room feel. You've got the amp give it a try you can always go powered whatever later, but you have to try it to know. Same with cab sims. Do I like all of them? No, but I do like a lot of them. Does an AC30 amp model through a Valve Jr sound like an AC30? Not exactly, but I get a good sense of it and it absolutely spanks any AC4 I've been around. Does a Special 6 with a blackface amp model sound like a 64 vibroverb? Not quite, but I like it a lot better then the super champ xd I used to have or the blues Jr for that matter. The point is try it for yourself. You will be surprised at the versatility it affords you. I started this because I needed decent tone at low volume, what I found was a setup I like better then any modelling amp I've ever plugged into and I've plugged into a bunch. Good luck.
