No longer a fan of M-Audio because of driver support.  If you want to spend some money and will pay for itself over the years and best driver support ever would be an RME product.

Very interested in the Steinberg now, too

Interesting . . . while I could never dis M-Audio, since I had one of their PCI audio interfaces perform for me very well for 15 years, though after my Win 10 update, it became clear I needed something newer, so I have found the Steinberg UR22-MkII to be very solid with Sonar Platinum on my laptop. (On my desktop I went with M-Audio M-Track QUAD) You are correct, it is all about the drivers, especially matching the drivers to your current OS and Sonar version, but always keep the future in mind, if you ever upgrade your Sonar version or your OS version.

But, it's all about the drivers, right??  :)

Just as a data point: My current audio interface is an old M-Audio FW-410 - used in Win 10 Pro!
 
Turns out the last M-Audio Win 7 (64-bit) FW-410 driver (5.10.0.5058) WORKS just fine in my Win 10 Pro - good thing too since I dual boot Win 7 Pro and Win 10 Pro and didn't want to have to buy a new audio interface.
 
My machine is a self-built workstation (multi-purpose machine: DAW, gaming, and an actual "put food on table" work machine).  The MoBo is an ASRock P67 Extreme4 Gen3 and I use the MoBo's FW port.
 
That is in spite of the (incorrect) rumor mill that was saying Win 10 wasn't going to support IEEE 1394 (aka FW)  anymore.

Same here.  I had originally bought the FW-410 10 years ago to use with a Dell P4 laptop with Firewire as a portable DAW (Sonar 6) recording rig.  The laptop has been retired (it actually still has Sonar 8.5 installed), but when I built a new desktop/DAW studio/workstation I no longer had any PCI slots for my M-Audio card.  So I bought a PCIe Firewire card cheap and hooked up the FW-410 on Windows 7 on the new PC.  No issues with Sonar, sounds great.
 
The funny thing about these M-Audio drivers is, they actually work better now with my mobo and Intel chipset on Windows 10 than they ever did on Windows 7.
 
I could NEVER get sleep to work with the Firewire connected. It would crash my system. Blue screen, with a debug pointed right at mafw.sys every time.  Even some warm reboots occasionally blue screened for me.
 
But on Windows 10, this thing sleeps like a baby now!  Reboots are clean now too.  Happy!!!
 
As a loyal Midiman/M-Audio customer over the many years since I first set foot in the Cakewalk/DAW world, I am sad to report that it's no longer the same company.  It has been acquired and sold a couple of times since the FW-410 was made.  So I no longer feel that I would trust them enough to continue buying their products.  They seem to be quick to end of life their products and/or quit development of their drivers.  I bought an Axiom 49 and called their parts department a few years later for a spare part.  Sorry!  But we have a new version of the Axiom we can sell you !  Ha!

I still use an M-Audio 18/14 without issue.  I was upset they didn't update it to have a Win 10 driver.  However, it seems to work flawlessly under Win 10 so far.  Thus it still works just fine.  
 
They are lazy and should update/support the drivers for older hardware and my future purchase will reflect that even though this one happens to work now.

For price vs value vs quality I'd definitely go with Focusrite as others have already mentioned. My 18i20 has been rock solid with Win 10/64 bit and Sonar Platinum. Very good pres and A/D's too...

I upgraded my M-Audio M-track to a Focusrite 18i8. I'd say get the Focusrite. Lot's of quality for a few bucks more. Worth it.

Actually those run pretty good. I have one.

I have several audio interfaces, including an ancient Kore 1 from NI that is likely over 10 years old now.
 
My primary audio interface is a Presonus AudioBox 1818VSL, with an 8-port light-pipe expansion unit for a total of 16 ports.  LOVE that.
 
I also have a Yamaha/Steinberg UR22, and that too is rock solid - running in Windows 10 connected through a USB 3 port with no issues.
 
I also had recommended a Focusrite unit that was comparable to the UR22 to a friend of mine, and that has worked flawlessly for 2 years now for him.
 
And, I cannot recall ever seeing anything bad posted about the RME units, though I have never seen or used one.
