NVME Recommendations for Mobos w/o M.2 or U.2 slots

The combination of improved Linux support and reduced costs have me contemplating getting NVME... finally. Over the years I've noticed quite a few Linux guys opting for the Plextor PCIe card versions because they don't require special drivers while offerring substantially improved performance over SATA interfaces. I wouldn't be surprised if SATA didn't last another 3 years.
Since Plextor introduced those around 5 years ago, there are now lots of non-SATA NVMEs around at reasonable prices. Unfortunately the field has not "settled down" yet so the purpose of this thread is to
1) Insure Linux compatibility (my mobo is Asrock Z77 Extreme 4 with a Bios that handles NVME)
2) Get the best performance bang-for-buck
3) Not lock myself into hardware that won't transfer well to a newer mobo in a year or two.
So, I'm thinking an adapter card for a PCIe x 16 slot is probably wise... BUT I see that some rather severely limited performance NVMEs get "pawned off" as PCIe compatible but are still stuck at SATA or only slightly better bandwidth speeds. Those will never come close to saturating the bus. It's basic marketing it seems.
So my first question is.. is U.2 enough superior to M.2 to ignore M.2 or is M.2 where the better bang-for buck reside for the next 5 years or so?
Right now I'm looking at comparing the M.2 GIGABYTE AORUS Gen4 AIC Adaptor GC-4XM2G4, Easy One Click RAID, Full PCIe 4.0 Design, 4 x PCIe 4.0/3.0 M.2 Slots with Syba SY-MRA25060 2.5" U.2 NVMe Drive to PCI Express x16 Slot Card or SATA III SSD/HDD PCI Mount and for drives I'm looking at ADATA, Samsung and Intel but Seagate has Enterprise drives on sale like the Nytro series.
I want improved performance I can feel (compared to SATA III mechanical drives)but reliability and compatibility is very important. Obviously since I've waited this long for any SSD upgrade, cost is an important issue but I'm willing to spend up to ~$400 USD to get decent tradeoffs.
So... U.2 or M.2? for starters....
