I looked at the 2320, 2620 and 2920 and ended up with the 2920. I do think the difference is noticeable, but its really more at the PTO. If you run a PTO HP intensive implement like a wood
chipper or generator then the increase in HP is very important. if you don't then realistically I don't think either tractor has enough traction to be HP limited. (I think I've managed to to bog my
b2920 twice with non PTO activities, once by pushing on dry pavement with lots of weight and traction and another time pulling in the same situation. It all comes down to your use. The 2320 has a different loader and a few other small differences, so that one has more differences than just HP
