Well I can give a little input I think. I would say that the 2094 and stihl 066/660 are different saws. The 660 is higher strung and may be as fast or faster in standard bucking in moderate sized wood, but the 2094 is definately the saw (of these two) I would reach for if I were going to be sinking a 48" bar all the way in hard wood. An early dual port square top 066 magnum might hang a little better, but i'd still give the big sweede the edge with bigger bars. The closest thing to a 2094 aside from a 660 would be a Husky 1100/2100/2101 which I think would be pretty close with larger bars (maybe a slight edge to the Husky...maybe) or a dolmar 153 Which I would say is the most similar cutting experience for me to the 2094. Those153's have some revs too, but the thing I always liked about them (and the 2094) was their lugging power in larger wood. I would say of all of these the Dolmar has the most usable/comfortable handle arrangement followed by the J-red then the Husky with the Stihl bringin up the rear. I will add that the dolmar, all it's other virtues aside, is terrible on gas compared even to the Husky which is the same vintage. Also an advantage the Dolmar and husky have is the manual oiler backup which I think is important on saws this size.
