The Alexander and Savic Plaza are slightly less bulky, footprint wise as they are both 50cm deep whereas the Barney is 54cm deep - it might not sound much but it does make it stick out quite a bit further (but also gives loads of extra floorspace!).

My choice would be the Savic Plaza - it's a good size and a bit front door is good for interaction and taming and just doing stuff in the cage - plus you can attach things to the roof as no door on the roof. It is a couple of cm taller than the Barney so needs the base filling with substrate to avoid any fall risks and any hard items under a shelf. The downside is it needs a house really and that would cost extra, although you could make a cardboard shoe box house.

If I didn't have the Barney I'd get the Plaza
