I have owned bows from all three manufacturers. All 3 make great bows. IMO Mathews puts the most quality into their product. This is evident when you compare components and tunability.

Bowtech has had some problems with, what I believe to be, rushing products out to retail before working out kinks. If you don't believe me, I'll let you hold my 05 Black Knight limbs which are splintered or my 05 Allegiance (80#) which ,of all the bows I have owned in my lifetime, has been the hardest to tune. Centershot and Cam lean nightmares..... I am hoping to try an 06 allegiance to see if they resolved their issues which do exist. I like the fact that their bows are fast as hell, just let me be able to tune the damn thing without having to buy specially made equipment for their mistake of a 1 1/4" off the riser centershot. (allegiance)

Hoyts are quality bows. Xtec or Vtec are the latest ones that I have shot/tuned and they had good centershot and were very consistant at the range.

The bow I currently shoot is the Switchback XT. Love it. Tuned fast and yeah silent and smooth.

In conclusion, Bowtech for speed, but possible problems. Mathews for smoothness, silent shooting, and IMO highest quality. Hoyt for a slight combination of both. But the key is, go out and shoot em all and try to tune em all. You'll know what to get.
