There are pros and cons to both products. BIN brushes on smoother because it's super thin, but it will dry out on your brush pretty fast. You can clean the brush periodically to prevent hardening on the bristles. You need to cover everything very carefully if you brush BIN, or even Cover Stain because both products sprinkle everywhere, and they're both very messy to brush and roll, especially BIN. Both are excellent sealers and stain blockers. Either one would be fine for primer on your cabinets. Cover Stain sands a little easier than BIN. If you get some brush stroke marks in the Cover Stain, you can sand them out when it fully dries. It sands into a fine powder. If possible, I recommend spraying instead of brushing and rolling. BIN lays out really nice on cabinet doors when sprayed flat. Your overall finish will look a lot better and you'll save tons of time.
