None of them are superior to the other. I would look at holding tank capacities, payload capacity and go from there. Normally I would've picked the Imagine over the rest but after viewing a post on the Grand Design owners forum about a guys Reflection rear cap getting ripped off like a sardine can I will never own a GD product. I know that getting good help in the RV industry is tough today with the current boom going on, but with the rear cap off you can see many assembly procedures.
We had a North Trail 26LRSS as our 2nd TT. Had it for 2.5 years. Only interior issue was the hidden hinges kept popping out of the cabinet door. Some Super Glue applied to the plastic screw insert fixed it. I fixed about 5 of the upper cabinets that way. After a couple it only took 4-5 mins to fix.
I didn't like the way it towed either. A by product of the spread axles being to close to the center of the TT. I don't think the fact that they're spread axles helped at all.
I would look at Jayco.
