I don't like being cooped up.
But in a tight one... a built one, the scent is almost a non issue at times.
Pop up ones not at all. But I've sat in both a LOT because you can get away with a LOT... lot of movement, book reading etc...
ANd in reality, it doesn't much matter if I can see far or not, I can see past my chosen max distacne, and if they aren't in range anyway... not much I can do about it.
Its one of the easier ways for turkeys with a bow. Without one, they are VERY hard with a bow, having to wait until the fan blocks the eyes to draw, though that gives a really good shot angle at the same time.
All this being said I haven't sat in a tripod or such in years. and I have killed my 3 biggest bucks out of a box...
