I have built alot of cages in the time I've had rabbits. I've never been 100% happy with any cage. I also find it's more about the entire set up as a whole. Make sure the cage height is right to be comfortable. Cage doors and nest boxes aren't the wrong size for each other. Cage doors that open inward always make the rabbit irritated at the door coming at them in my experience.
Back when I had alot I would have been happier if I'd gotten or built a bunch of the same cage/hutch. Not a hodgepodge of a different ones.
