I can't imagine why they'd have bad reviews? Like, it would almost seem like it would have to be because of personal preference or something. Anyway. Dress forms are nice but they don't have arms so they just flop. A manny is arguably best. Personally one of the annoying things about them is having to take the arms on and off but that's just me being lazy. I think clothing will look best on them.
I also think using one shows a level of commitment that may subconsciously factor into people's confidence in buying from you. Or not.
The one I bought is fine. I prefer the straight arms, seems like it would be easiest to wrassle into clothing. This is Blair: https://www.amazon.com/gp/product/B07FR2LQH9/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1
