How useful is standing medium punch (close version) as an anti-air?

Been tinkering with using this a little more as I found it was useful in sending people back when they try to jump over you from close range for a cross-up. Timing is a bit tricky to get down pat, but i found it works well when timed right. Anybody put this to use with success or do you have any other tech for dealing with people who suddenly decide to jump over you from close range?

I’ve been using it for a while.
It works great vs air tatsu and claw’s specials.
