Push 1 is still awesome and there's a ton on the second hand market for a fraction of the price of Push 2. You get way more than you pay for at those prices.
I'm happy with mine, I like the pads and it's fine for sequencing and playing. It still receives updates and improvements.
I do like the screen on Push 2, it looks like a nice update, but you are paying a lot for that screen, so you better use it!
I also own a Maschine Mikro MkII by Native Instruments, it's my go-to machine for finger drumming beats and sonic experiments... great pads, very precise, compact and enjoyable. The Maschine software is very good, and the add-on sound packs are great quality.
