O8 newbie here, take my words with a grain of salt.

23 is a decent low, but I want more options. I don't think it's necessarily strong enough to take without any other benefits (options for high, suited, whatever).

Being an O8 newbie, I think of it this way -- I have six two-card hands; I'm not going to play on the strength of just one. A2 is better because of the ace, in case I get counterfeited for low, but I still like to see more options -- suits, more low cards, etc. Not that I'll fold a lot of A2 hands, but the more I have, the happier I am.

Long story short, 23 is good, but not enough to merit play with two crappy cards alongside.
