I've shot them both. The Limbsaver is smooth, fast and shock free. If you can get past the funky looks, it's really nice. The DXT is nice for all of the above reasons too, but I just didn't shoot it as well due to the short ATA length. It wasn't as stable for me. It would make a nice blind bow though.
I SHOT AT THE INDOOR VEGAS SHOOT THIS YEAR AND LIMBSAVER HAD THERE NEW BOW THERE AND I SHOT A FEW ARROWS OUT OF IT AND I WAS IMPRESSED WITH HOW SMOOTH AND FAST IT WAS.TWO OF MY BUDDIES SHOT IT AND ARE NOW THINKING OF SWITCHING OVER.
