Have a Triton TX18. Bought it last year. Love it. Great fishing platform. You can easy fish two people on front deck. A LOT of storage.
Mine is rigged with my 2010 Etec 90 hp. If I could have afforded a 115, I would have gone that route. Boat rides nice. Handles rough water pretty well, but your not going to be running all out. I've added a 6" JP to mine and I'm turning a 18 pitch prop at 43 mph. That gives me a comfortable cruising speed of 40 mph. Most 115 owners are in the 46-49 mph range.
Ranger seems to be the popular version, but I think that's mostly dealer and name recognition. I liked the Triton dash better. All welded trailer. My dealer was willing to rig my motor.
The only knock I give the hull is it can have porpoising issues. The factory tried to cure this by welding aluminum angles to the hull back by stearn. They are effective at helping control the handling, but caused most hulls to loose 2-3 mph. Adding a 6" JP and proping correctly is a better cure but the JP will void Hull Warranty if discovered. I believe you can now special order them without the trim angles and a 4" fixed set back plate.
