Gen 5 47 or Gen 6 17?

Hi!

I have a Glock 19 Gen 5 right now that I'm pretty happy with but I've been eyeing also picking up either the Gen 5 47 or a Gen 6 17 and can't decide which direction to go.

The 47 is mainly attractive because Gen 5 has been on the market a lot longer and due to the shared parts compatibility with my 19. But, the Gen 6 upgrades are all things I'd probably be doing to a Gen 5 and I'm wondering if it's silly to not just go with the latest and greatest.
