I have the Laser Max, but I can't really compare it with the CT, since I haven't used the CT. The laser Max is okay, but not perfect. The switch is easy to activate, yet not too likely to accidentally activate. The fit to the gun is very good. I've seen people complain that theirs can be wiggled around, but mine is rock solid and seems to be part of the gun. The setting of the beam DOES seem to move around a bit from shooting. I've only been shooting with the laser on about 15-20 rounds out of each range trip. Every time I go to use it, I have to readjust the beam by an inch or 2. The adjustment is a lot coarser than you'd want it to be. Just the slightest bit that you can turn the adjustments changes the beam by a couple of inches. Because the laser is so far below the bore, parallax is a problem. It sits about 1 3/8" below the bore axis, vs your iron sights which only sit 5/8" above it. Doesn't sound like that much difference, but it means that your elevation setting is only accurate at ONE distance. Haven't tried calculating the geometry, but if you sight it in at 20 ft and shoot at 75ft, you'll be off by not just 1 5/8", but more like 10". You'll get the best results by sighting in as far away as possible. The parallax on the CT looks like it would be similar. The beam on CT grips is typically much closer to the bore axis. Would I buy it again? Well, the jury is still out on that. I can consistently hit head shots on a silhouette target 75 ft away--IF I've just adjusted the beam. So far I've found it more useful for dry firing practice than for shooting.
