That would actually push me pretty strongly towards Delta. United seems to be willing to sell even the very last seat for paid upgrades, meaning that I'd basically never expect to be upgraded on the transcons. On Delta I've been upgraded almost always using a RUC (and you could get up to 12 per year if your international travel is all going to be in paid business so you don't need the GUCs).
