I have the ultratec so I may be a little biased when I say it's better. Their both fine bows , I chose mine based on the feel , I like the Hoyt grips over Mathews. As far as speed? It depends on which type you get. I have the command cams (double cam) and with a 400gn arrow I'm shooting in the upper 270's at 65lbs. I wouldn't make your choice based on speed. If you like the smooth draw (and accuracy<img src=icon_smile_big.gif border=0 align=middle>) of a double cam , go with the command cams. The command cams have an excellent fine tune draw length adjustments which dont require a bow press. If you want a solocam , the versacam is very nice. The versacam has the draw length adjustment and the back stop adjustment.
Dont base your decision on speed or adjustment , base it on which one feels awesome in your hands. Their both great bows!
