OP should look at Outdoors RV. They're on the same level of quality as Lance but (IMO) have better floor plans and standard features. The fact that ORV comes standard with MorRyde suspension and Goodyear tires sets them apart and is a huge plus for me. Several models come standard with solar and are prepped to easily add more.
The Lance has better options with interior choices and galley equipment. I don't like the Lance roof because it's flat and thin and is prone to flex when you're up there working on it. I really don't see how 1.5 of compressed foam is better than a truss system with pink insulation. Neither is really "4 season" and each has positives and negatives. The Lance is certainly lighter. The ORV, like their sister company Artic Fox, are some of the heaviest modern TTs out there because ORV assumes some use off of paved roads.
The Transcend is the "entry-level" at GD with aluminum sides and the Imagine is the upper-end model with laminated walls and full walk-on roofs (all the GDs have the same roof structure). For the money, the GD is a great value. We've compared the GD, the Forest River and the Lance all at the same time. I don't see how anyone spends money on anything by FR, the fit and finish is terrible.
My rankings: ORV Titanium>Lance>GD>anything by Forest River dead last
