For rechargeable, it's hard to beat Pila in terms of size/brightness, not to mention runtime due to its li-ion battery. My 9AN has been moved to the bottom/back of my drawer for quite sometime. However, I admit that I like the look of 9AN more than G4R although G4R is brighter, smaller, whiter beam and longer runtime.
Since you have M3, you could simply get Pila bat (and spares) to run it at the expense of runtime. M3 couldn't use the 168a bat that is 80% more capacity like G4R though.
Unlike 9AN, 10X has a pretty white beam. If you prefer SF and found a way to carry the 10X, it might be a good choice.
It's too bad that L7 doesn't work on 9AN. Or else, my dusty 9AN might have a new life🙂
Hopefully, SF would develop li-ion based rechargeable light soon. By then, many of us would go broke🙂
