chrome OS tablet vs android tablet

I have an android tablet and a chromebook (which I'm posting with now). Chromebook is way faster and more stable than Android. I know some chromebooks can install apps from play (sadly, mine can't AFAIK) so they have all the advantages of Android plus better security, easier mantenance, etc. Android tablets have always been treated like the red headed stepchild in the Android world where Chromebooks are very mainstream. I'd go Chromebook all the way.
