Personally I think the only way one may work/look better than the other is if you use their full system - either mfr...as it makes sense that their spray is meant to hook up better with their seal product, etc...I certainly hope there's a clear winner!
trust me they work....I would think in the prof detailer world, someone looking to maximize his billable hours and get more jobs in a day, the simple fact that you can get a gloss fairly equal to conventional waxes and save the buff off time would make it very desirable....no buff, no q tips!...on to the next job...I don't doubt that many here may be able to tell a diff, but to the non anal, average joe client that just wants his car cleaned up, this would be a hit for the detailer....I know I appreciate the 20 mins of buff time of my life back....
