Agree 100 with both of these: Quite honestly, I've only ever owned 1 amp that usually gets modeled, a Mesa Dual Rectifier, and that was almost 15 years ago, so, I wouldn't know "accuracy" of ANY models if you hit me over the head with it. Just like you, I go for what sounds good. Modelers give you a great starting point and the convenience of having so many tones in one spot. Same same. I've been wearing earplugs on stage since around the year 2000, so, I totally get that. I'd argue that IEMs are maybe even a better experience, due to how much you can tailor what is going to your ears, (I use a stereo FX processor, split my guitar wide L/R, EQ it, and add some reverb/ambiance), and most importantly, my tone is EXACTLY the same no matter where I am on stage, or which way I turn my head.
