It appears to me that betting a half pot is slightly better than going all in, but it's difficult to say as it depends upon what assumptions one makes about the probability of being called. Betting a half pot, the plan is to fold to a raise. I estimated that half-pot bet would win 60% of the time. I estimated the all-in bet would win 85% of the time. (do these estimates seem reasonable?)

If there's an Ace on flop, that would seem to edge even more towards a half-pot bet, but OTOH on a board with a lot of draws possible, the half-pot bet might be worse as it would be goading someone into coming over the top when you couldn't call.
