Capital One forms the second tier of points programs along with Citi ThankYou Points. The program has a lot of good partners and it is worth accumulating Capital One Rewards — there are just fewer cards and options to rapidly accumulate points.
Capital One has one of the best mobile apps and points from purchases and welcome bonuses seem to post basically immediately.
Unfortunately, Capital One business credit cards are reported on your personal credit score so count against your 5/24 total.
Capital One has a really wide variety of partners that are easy to get a ton of value from including Air Canada, British Airways, Singapore Airlines, Turkish, and Virgin Atlantic. Advanced users are happy to have programs like Avianca, and Etihad.

It’s generally very poor value to transfer to these partners.
