Travis, in general I prefer Polystone over fabric mainly because since I have an open display unit with no glass doors to enclose my collectibles, the fabric some of these figures come with is a magnet for dust. I feel there is a bit of misconception as to what these collectibles are because they are not solid sculpts, they are plastic and are articulated like dolls or toys. There was time when I felt that way, but I had a change of heart after noticing time after time the quality of these pieces. They are just another option to the characters we choose to collect.
In my view, Hot Toys produce some of the best likeness out there, and the tailoring of the clothes and details for these figures are fantastic. Just looking around at other people's collections that include Hot Toys, it is easy to tell these figures are worth their price. The only downside I see to them is (again) maintenance if you have an open display and you have a ton of them to care for. Boba Fett's outfit is made of some fabric but not entirely, so I think it would be fine. Fabric aside, the figure is beautiful and I'm sure you'll be pleased with it, plus it comes with a bunch of accessories and because it is articulated, you can also pose him anyway you like. If I were into Boba Fett as much as you are, I would definitely get it.
