I've owned about every hardware acoustic amp sim at one point, not real impressed. I make Synthedit/synthmaker acoustic amp sims, and I like them. They're at Acousticology processes minimally, the other 2 are split for elec/acous, the 1st 3 presets in each for elec, the 2nd 2 for acoustic. Nowadays if you want an amp sim you have to make it yourself, manufacturers aren't going to up the quality on those.
