Zero issue with either coming loose if we’re talking valve stems (bodies). The e13 uses a hex key (internal) and the O-S uses a box wrench (external) which is clean.
I don’t have issues with Stan’s coming loose - I use vice grips. But definitely not as clean.
If you’re talking valve cores they all can come loose especially if you use a thread on pump like Lezyne. The e13 valve cap is a stem tightener which is cool. The Orange Seal (and Schwalbe) valves come with a little plastic tool to throw in your tools. Some - not all - chainbreakers can be used to tighten valves and I carry a Leatherman usually as well.
If valve cores come loose regularly on you a dab of blue loctite on the threads will probably make you happy.

Valve cores can be a PIA to acquire - and now that so many people run tubeless robbing your friend’s flat tubes isn’t an option - and they’re the wear item in the tubeless valve set. To my knowledge Orange Seal are the only company that includes spares.

*edit: Mis-read your question sorry. e13 has really impressive air flow.
For the record I’m at peace with my level of bike-nerdiness... I reviewed those too [**here**](https://nsmb.com/articles/reinventing-tubeless-valve-e13-ethirteen/).
I’ve been really happy with both products but - guesstimating what the O-S will sell for - I would probably buy the Orange Seal valves for my own bikes simply because the performance and quality is equitable to me and that means they’re a better value. I reserve the right to take that back if they’re more $ than I’d guess.
