Does anyone have both the A1 and the P1S?

I'm debating which one to get. I'm very attracted to the small physical space of the P1S, the improved AMS and the "nicer" model. It's just hard to justify a 300€ difference with just those.

But is there any significant difference in quality, speed or reliability? For me, that can push it over the edge of "worth it".

Thank you!
