Well, the question is, why you have Choice in the first place. If it's for small towns iwthout "the biggies", then Choice, TripRewards, and Best Western are the main players there (in terms of points-based chains). Of those, only Choice has good points promos. And TripRewards has threads like "is this the suckiest program ever", and Best Western has points problems all over the place (although their customer service on the phone seems to be pretty good).

And if you're willing to stay with high-priced chains only, that implies your stays are mostly not on your own dime (or you're not price sensistive), so that wasn't presumably why you went to Choice.

If it was for the promos, Priority Club is the only chain that I can think of that can come close to the points earning potential of Choice with as few stays, but there it's not from one official promos but rather by being able to "stack" multiple promos simultaneously on the same stay (tho not as much as a few years ago), with many of those promos only found on FlyerTalk and nowhere else. (But if you're getting promo codes from FlyerTalk, that raises new customer service concerns, as you don't to raise flags with customer service that you register for promos they never told you about! So those who stack promos like this tend to try to avoid calling PC's customer service when at all possible!)
