The Inspire, a nice coach, is not in the same league with the other two. In your heading you mention the Beaver Patriot, depending upon year and engine size, a respected coach.
I own a CC, and like the line in general. The CC Lexa, was I believe a flagship model for CC. You might make a call to Oregon Motor Coach, and Country Coach, or look up Kevin Waite's phone number and call him. The Lexa was for sure a small volume number built coach. Checking with those groups or Kevin, could give you a feel for if the complexity is a concern to be aware of...
Executive could have the ISM in it, which is a fine engine. Suspect the Lexa has a BIG CAT, which would also be a fine engine.
All things being equal, buy the coach you feel fits your living style the best, yep, even the Inspire
! (Again, a fine coach in itself...)
Best of luck to you,
