Thoughts on iFlight 7" Quads?

I'm looking at the 7" iFlight quads and I'm wondering how different they really are from each other. There's the Chimera 7, Nazgul Evoque 7, and CineLR 7. I'm doing cinematic flying mostly. I like iFlight because I've had good experiences with them before, and they have side panels, waterproofing, stuff like that. The CineLR seems like it's aimed towards cinematic flying but I like the evoque's more robust Borg stack. Are they all pretty much the same or are there noticeable differences?
