I almost didn't include Cheesecake Factory on the list because it is better and more expensive than the rest of the field, but I figured that since the food is basically the same, comparison is fair game, especially if you take price/value into account.

Separately, I just added Red Lobster, Maggiano's, and Carrabba's to the list in the OP. With respect to Red Lobster, I honestly don't know the difference between it and Long John Silver because I never eat at either, but I suppose the former at least looks more like an Applebee's from the outside. I was tempted to add Legal Seafood and McCormick & Schmick's as long as seafood specialties are okay, but these are starting to push the limits of the category (e.g. it's not hard to top $100 pp at either...though both have great happy hour deals).

In any event, all suggestions are welcome with respect to the list itself, and what parameters should define it.
