Another +1 from me for the CalDigit TS3+ dock. I've been using it for about 1 1/2 years now with dual 4K UHD @ 60Hz displays, and haven't had any issues whatsoever. I also use it for a wired network connection and several USB peripherals at the same time. I really appreciate its layout where most ports are rear-facing so that you don't have cables on your desk coming out towards you and then looping back. The additional front-facing ports are great for popping in the occasional flash drive when needed. For some people the 87W output may not be enough, but it's never been a problem for me.
