Here are key points about the ASROCK X399 SLI PLUS.
VRM Quality and Cooling: ASRock maintained an 8+3 phase configuring for the CPU VRM that uses 60A power stages and 60A inductors. They then went and slapped on a huge heat sink, so that the VRMs could be easily cooled down. The results are excellent; the motherboard can handle an overclocked 16-core CPU with ease.
Platform Features Maintained: All of the CPU's PCI-E lanes are still being offered to you. You get three x16 PCI-E slots that run full speed at all times, and you get three M.2 slots that run x4 PCI-E 3.0 at all times. The motherboard also kept the eight SATA ports and offered up a lot of USB 3.0. USB 3.1 is integrated on the rear IO.
OC Features: Power, reset, and clear CMOS buttons are a nice touch, but ASRock took it a bit further. They added a POST code display, which is awesome, and they went ahead and integrated USB BIOS Flashback on the rear IO.
Micro-ATX: The X399M Tachi is your only option for a mATX X399 motherboard, and it's a solid option.
2-Way SLI/CrossFireX Only: While you theoretically could get 3-way to work, the spacing requires make this pretty much impossible without some type of breakout.
The ASROCK X399M Taichi is a loaded motherboard with a solid feature set and quality components. The WIFI controller isn't the best in class, but pretty much every other component is. The motherboard is the first of its kind, and since many people have been asking for smaller form factor motherboards for the X399 platform, we see it being a popular product. It's a solid product all around and offers pretty much everything you might want in an X399 motherboard, so give it a look if you want a smaller TR4 build.

The Bottom Line: As the first mATX X399 motherboard the X399M Taichi had a lot to prove, but delivered quite admirably.
