UA changed their upgrade system to be points-based, where the class of service, length of flight, and the fare purchased influences how may of your 320 PlusPoints it takes -- if you are upgrading discount long-haul Y to J, you effectively only get four one-way upgrades. They also provide the opportunity to earn more PlusPoints through spending, which may influence some people's decisions.
If you prefer complimentary domestic upgrades, note that UA does not provide any CPUs on its domestic business routes (EWR-LAX, EWR-SFO, soon from JFK as well). If you want an upgrade on UA on these routes, you'll need to use miles or PlusPoints. DL provides complimentary medallion upgrades to domestic D1 on the day of departure, and AA uses the standard upgrade windows.
If you are flying long haul international business, the Polaris lounges are supposed to be quite nice.

I was under the impression that the upgrade priority for Delta 360 was the same as DM -- DL has never said anything publicly about it, but that's based on what's on the internet about it and conjecture.
