No, 3-betting is easily better. There is virtually no one at 6-max 25NL tables (at least, when I played those games) that doesn't open the button at least 25% and you're crushing that range. Furthermore, you will be 3-betting light more often in this position than probably any other and in response, the BTN flats with hands like Ax/KQ so it's important to have more hands for value that crush that range as well.

I'd be more inclined to flat AJs type hands that have roughly the same hot-cold equity but can continue on far more boards postflop.
