I think they all look like cheap plastic boxes. If you're after a higher end installation I wouldn't use any of them. You can build your box into the wall and tile it.
In my case, I put in front load washer and dryer and installed a counter above the machines, with a tiled backsplash. Getting the hoses up through the counter would have been pretty ugly. So, I got a pair of Chicago Faucets wall valves (other manufacturers make similar valves, you can find one that fits the style of your laundry room) and brought the water supply lines out behind the machines (under the counter) so you don't see the hoses at all.
I also used an electronic water sensor to shut off the motorized ball valves at the outlet, in case the hoses leak or burst. The system also turns off the electrical power to the machines if a leak is sensed so that if the water is due to a drain leak, the washer will stop pumping the water out.
