Delta: While it varies by market (and at times DL will match the ULCC with close in highly discounted fares) Delta is mostly doing these only advanced purchase fares in only the very lowest buckets.
United: So far no evidence of an advanced purchase requirement and -N fares appear to be in all buckets up to M. So someone on a very expensive ticket can get a -N

Delta: Restrictions on upgrades and seat assignements, but no limits on FF credit or carry-on bags
United: Also restricts carry-on bags and gives no status or lifetime credit for the flights in MP

Delta BE fares are designed to compete head with Spirit, offering a similar fare, with some restrictions (no seat assignment, upgrades) but some benefits you don't get flying Spirit (carry on bag, FF credit). What United is doing is VERY different, it is basically debunding certain benefits and then trying to charge everyone an "up-sell" of $5/10/15 for them each way.

IMHO this is not going to be well received by the public, and in particular business travelers.
