You are good to go with any of the photo-realistic silos. They are all comparable in quality and price.
I would shy away from the collapseable shells. I've never owned the ones in question, but I have owned "cheap" decoys before. They are great at first, but you start to lose interenst fast and get frustrated with them. Difficulty in setup, small size, paint durability, overall appearance all start becoming aparent after the luxury of buying new decoys cheap wears off. I baught a few dozen collapseable decoys (not the same brand) a few years ago and I don't even take them out anymore as I have had more problems with them than I care to get into.
I love my job, it fascinates me. I can sit and look at it for hours.
