I currently have both, a 62", 50# Silvertip, and a 60", 49#, PSAX Widow, and both are fast flight. I enjoy shooting both bows and it actually depends upon my mood as to which one I shoot the most at any particular time. I have owned the Widow since 2004 and I purchased the Silvertip about 1 1/2 years ago from a fellow TradGanger. I hunted with Widows for years and have taken my share of game with one. I hunted this year for the first time with a Silvertip and was quite pleased and successful. I have hunted with both and I have shot 3D tournaments with both and both bows are great shooters. My current feeling is if I am going hunting I will pick up the Silvertip because it is a tad quiter, but if I am going to a 3D tournament to try and win I will pick up the Widow because I am able to consistantly hold slightly tighter groups with it. I believe the Tip has a slight edge in looks compaired to the newer exotic Widows, but in the last few years the Widows are making a move in regard to aesthetics. My advice would be to get one of each because they are both a pleasure to shoot.

P.S. I also agree with Cory. It appears to me the Tips are able at lower poundage to handle heavier arrows a bit better.
