To the op,
You specifically asked for the opinion of them 2 cartridges.
Having both cartridges in my safe and using them constantly.
I will vote for the .17 Remington easy to load for and readily available brass and some availability on loaded ammo.
Don't worry much about the carbon fouling..
It would also be a personal opportunity to get into reloading.
Note", .17 Remington lacks the availability of quality bullets..but" inside 200 yards is lighting.
