For me schrader has been less hassle to use.

If you unscrew the core and/or remove the spring the tube is just as easy to deflate.
Valve leaks are rare, even if the spring is removed, and a good gasketed valve cap will stop them.
I like that the delicate parts are recessed out of the way.
No adapter needed.

For many years I had only one bike remaining with presta, the one with the narrowest rims, but I finally decided to convert it so I am now 100% schrader.

Before and after:
