A put bet is like a come bet made after a point has already been established. I don't recommend put bets because the value from come bets comes from the first roll, before any point is established. On a the first roll of a come bet the probability of winning is 22.22%, and the probability of losing is 11.11%.
However, if you must cover other points quickly, the odds are generally equal or better on place bets and buy bets on the 4 and 10 (assuming commission paid only on a win). Only if you can get 10x odds, and take them, do put bets become a better value than the better of place and buy bets. Since so few places offer 10x or better odds, it is safe to say to just avoid put bets completely.
