You have nearly the same equity on both streets (~0.7% more on the turn). It is mathematically incorrect to count your equity on both streets unless the betting is closed (i.e. all-in on the flop). Raising to get it all in on the flop is correct, since you are the favorite to win if you do.
Failing to get it in on the flop, you are now NOT all in with only 1 card to come... now you're ~33% to catch your draw (with 15 outs OESFD), and should bet accordingly (PSB).
