1) For under $200, the motherboard has quality vrms that can handle those monster 12 and 16 core processors (Hardware Unboxed has videos that verify this). I have the board paired with a Ryzen 3800XT for a work and play build and I don't worry about overheating my vrms.
2) If you are into overclocking or just tweaking your processor and ram, all the parameters are easy to find in the bios. I don't overclock my processor but I see the many parameters while manually tuning RAM.
3) The RAM QVL list is extensive, which is a major positive when dealing with Ryzen builds. Find QVL listed RAM and you can turn on A-XMP to easily run your ram at the rated speed. I had no trouble with running Hyper X Predator 3200 CL 16 DDR4 RAM with A-XMP and was able to get better tuning with help of the Ryzen Memory Calculator
4) Two M.2 NVME SSD slots (Gen 4 and Gen 3) and 6 sata ports (none disabled when using M.2). This is a major plus if you run SATA SSDs and HDDs for gaming and mass storage needs while still getting the benefits of NVME speeds for booting and apps. The NVME slots come with removable heatshields, which is a nice bonus if you have an NVME that supplies its own heatsink
5) There's a switch for turning the color lights off on the board. Great for those of us who are more about function and without see through cases.
6) The IO Shield is integrated with the board. This is great for not having to fight with the shield when lining up your motherboard mounting.
7) Reinforced video card PCIE slot. Those gaming GPUS aren't light!
8) Onboard sound is solid quality and includes SPDIF output
9) The motherboard layout is great for accessing the various ports and installation hookups during a build
I can't think of much else to say. I've had this motherboard for a build since October and its having no problems being the heart of my personal use system where I practice programming, make audio for language learning, play some triple A games on Steam, and do other trivial things (web browsing, Office, etc)
So I sent back the mobo and got this one. Got the proper bios install file onto a thumb drive, put it into the proper USB slot on the mobo, pressed the button, waited with baited breath....and it actually worked. You can google the instructions. It's not too hard. So now I'm rocking the new Ryzen 5000 chip, this mobo was pretty easy to work with, seems well built, good connectivity, no Wifi but I didn't need it. You don't need to futz around with a back plate, which is a long overdue improvement in mobos as far as I'm concerned. I did have to go into the Bios and change a setting, UEFI to CSM I believe, to get it to boot out of bios and into the windows boot drive.
I do kinda wish there were a few more USB ports. But the fact that it was relatively painless to update this mobo's bios, and the fact that the process for doing so *actually worked*, is invaluable. I also got significantly faster transfer speeds via PCI between hard drives than I was used to with the old setup. I'm up and running and happy with this mobo.

Unless you have a UEFI/GOP graphics card or integrated graphics you can't boot into the BIOS to change the boot setting that makes it work without a UEFI compatible card. When I borrowed my brother's graphics card to change the setting it just changed back on its own and now I can't get into the BIOS again.
I've seen posts about people having this problem with newer cards as well. Unless you have piles of spare graphics cards laying around or you're buying a processor with integrated graphics i don't recommend this board
