Both are over-specced for the application and there is no reason for 316L unless you intend to do a lot of scuba-shaving. You’re being sold something because you’re told it’s “better” without considering whether it actually is for the job. This is a paper argument. In the hand you’d have absolutely no clue which is the “better” steel.
I noticed that there was Pils issue noted in one forum before, it was not made of 316L and got rusted. Might be different reasons, not sure.

Brands, whose razors are made of 316L, note that:
We need 316 SS to get sufficient corrosion resistance for the safety razors.
They might be corroded with time, due to tap water, humidity in bathroom, interaction with carbon blades and shaving soaps, etc.
I honestly don't have any idea whether 303 SS will rust or not within 10 years, or no idea to we really need 316L for safety razors.
But as much as I know, corrosion will not initiate instantly, it requires time. It is hard to know now.
Since, many CNC razors were manufactured less than 5 years ago.
I remember that some brands like Rex, Rockwell, whose razors made of 316L, give lifetime warranty.
Is it possible to get lifetime warranty against corrosion for Blackland Razors?
Also it could be nice if you can inform me about:
What is the machining cost or machining time difference, if you use 316L or 303 for your razors?
