I don't like the plastic crates because they are unnattractive and bulky. I have three wire crates in my home and I can cover them with piece of wood and a sheet and they look like a table. One of ours doesn't fold down and that one stays in the house permanently, but the other two fold down easily.

I prefer the soft crates over any other crate, but in the house, they don't look good. I do actually have two of my three soft crates set up downstairs because that way all four dogs are able to stay down there when we leave instead of two dogs upstairs and two down. I also use them in the car, on trips, at obedience class, at the park, etc. They are wonderful, I love them. However they are not very sturdy, and Luka and Mandy don't do good in them for long periods of time or if left alone. If I take either of them somewhere where I need a crate, I fold up my wire crate and take it with me.
