Which is better ipod touch 5th gen or ipod nano 7th gen.?

I want to know, cause I've been looking on Ebay and Craigslist an I cant find an itouch for 70 dollars that 5th gen. I was thinking maybe I should get a nanao or an iwatch which is better? State reason please!!1

well try getting a 4th gen ipod touch, first of all itll be cheaper, cause its older, you get the larger screen and camera, good for music and pics. and everything else. good luck
