360

Long story short, NEXDOCK makes the best lapdocks in general Uperfect makes the 2nd best, generally. They're typically based on nexdock designs, but usually are missing a usb port, and typically weaker battery Single best lapdock i have is nexdock 360 wireless The uperfect 15.6 dock is the 2nd best, and nexdock 15.6 (xl) is #3. (Udock has 120hz panel, xl 60hz)

Generally the Nexdock's are regarded as the best with a few different variants although I think only the 15.6" XL can be ordered "new" at the moment (depending where you are) - The Nexdock 360 is a smaller variant but I've not seen stock for a while. These are both touchscreen. There are other variants made by uPerfect and Dopesplay which are generally regarded as inferior to the Nexdock although almost identical. Personally I've currently got a Nexdock 360 and a Dopesplay DR148 and aside from the DR148 being slightly larger I honestly see little to no quality difference.

Have you looked at Nexdock? My Nexdock 360 is all aluminum with a keyboard and trackpad. Screen is just ok, maybe similar to what you already tried, but materials and build is very solid.

My nexdock 360 has an awful track pad with built in gestures that are a pain to disable
