I personally like them a lot (photon/genesis). Truth, in the 90's I went to hardboots to rid myself of strapping in. Now with these I can ride more mixed conditions/powder with soft boots and no infernal strapping in. HB's are great, but not in every condition. in fact I'm riding more soft than I ever have in 30 years.
Downside is that it can be difficult to step-in in powder.
The only other option I would consider is the Nidecker Supermatic - no dedicated boots. However I like the greater forward lean adjustability of the S/O's.
