I installed the Trektop NX last year and really like it so far. I personally like the fastback look, but that aside I like having the ability to remove the 3 windows & have a bikini top. Here in UT it's been getting up into "windows off" temps, but we're getting spring showers coming through and my TJ sits outside. In the past couple weeks I've removed & installed the windows twice so the wife can do her daily open air cruising, with some practice it takes me about 10-ish mins to re-install.
The reason I didn't get the framed soft top is because I have kids & dogs who all ingress/egress through the window over the rear wheel, and that frame would have been in the way.
And
@MtnRanger160 's idea about window storage is great. I'm going to do that same thing for our long trips this summer just in case we run into weather.
