I own, and use regularly, both the Progress XL (with a Cooncat Bob modified adjustment knob in Amboyna burl) and a chrome Futur. I love them both and they both give superb shaves. I would have to admit to a slight preference for the Futur, though, mainly because blade changing is slightly easier. However, I won't part with either one. Yes, if my hand gets wet and soapy, the Futur becomes a little slippery. I solved that by lightly rubbing a little alum on the fingers and thumbs of both hands--not original with me (it was a tip I read on one of the shaving forums). No slip and it doesn't feel sticky, either. One quick application lasts for the entire shave and works with any potentially slippery razor.
