many of the ones iv seen dont look to good, but iv seen some amazing looking ones. though due to the tight fitting part its a little awkward with it outlining most of the body..
though get a good quality one, and clothes/a costume over it and it will likely look amazing. you have what ever cosplay type of stuff like a suit of armor and then under it you have the fursuit. most of the benefits i see is that it covers those small gaps in armor like on knees/elbows so a little more realistic, and if you do wear any clothing/cosplay stuff over it heat will not be too much of a problem.
