I use mostly Unger gear, I like Ettore though, but I also think the Unger Swivlelock squeegee handle is a really good piece of kit.
I don't like the one Unger stainless steel channel though...the one with the serated edge for the quick release handles (Yes, I know it allows you to do away with the end clips to hold the rubber in place, but on an 18" channel the lack of rigidity allows the channel to deform to easily.
It's fine on the shorter channels though

Although I tend to only use Unger rubbers, I do think that the Ettore soft are the best on the market...though of course they wear out quicker
