I have handled both the first and second gen PPS's extensively. I keep a gen 1 PPS (M1) in 9mm. I like the gun allot . I think the features and ergonomics are better than the Shield 9 ( which I sold off.) . The interchangeable grip back straps and squared trigger guard make it shoot like a much bigger gun for me. Reliability is fantastic too. I think it's a great (and often overlooked ) option in a single stack, mid caliber carry gun.
That said, I used to carry it fairly frequently but have now somewhat replaced it with my PC shield 45. I still keep it for range fun though.
