As a 50,000 mile flyer on either UA or DL you will not be seeing that many upgrades anyways.
I've been considering DL, as well. I was DL Gold for years and liked it quite a bit. My company has a preference for UA but it's not insurmountable. The big difference in my mind is that I've had much, much easier UA redemptions lately, so whatever little RDM I'll earn would be worth more with UA.
