Welcome, again, to The Forum. So much of the trailer selection decision is based on personal use & preferences, that offering much advise without more info is pretty superficial. For instance: How, where, and when will you be using it. A trailer that is well suited for week-ending in Florida, may not be practical for full-timing in Michigan.
I'm a little partial to the Eagle, because I own one. Although a lot of folks dislike the fiberglass exterior siding, I think it gives a trailer a sleeker, more contemporary look. It also offers slightly better insulation for early/late season camping. The ceilings are also 3" higher, which gives a more spacious feeling - particularly nice if you spend a lot of time inside the camper (full-timing, cold or rainy weather, long winter evenings, etc.) With the smaller door-side slide-out, it also gives you a larger awning/porch area. On the other hand, the kitchen countertop space is very limited in this particular model. Where are you going to put your coffee maker, toaster, etc.?
The Jay Flight has more kitchen countertop space and slightly larger fresh, grey and black water tanks. (The tanks size may not be terribly important to you if you plan on using it mostly/exclusively at full hook-up campgrounds.)
Both trailers have virtually identical wardrobe storage, so that's pretty much a wash. I would be remiss if I didn't point out a personal bugaboo of mine: both trailers have rear entertainment centers. Unless you are sitting in the front dinette booth, you are forced to turn your head to the side to watch the television. If you live/camp in a hot, cold, or wet climate - or you are a full-time RVer - you may be spending quite a bit of time indoors watching television. After a few days of sustained head turning in a S & B house I use to own with a similar setup, I developed a nasty pain in the neck - literally! After I changed my viewing position, it took several weeks to clear up. As I said, that's my personal bugaboo. There are thousands of trailers & FW's out there with similar setups (either rear entertainment centers, or ET's between the living room and master bedroom), so it's obviously not an issue for everyone. JMHO!
Good luck making your decision, and enjoy your new trailer for many, many years!
