[Q] Gapps question topic

When it comes to gapps is there any reason to go with anything besides PA's version of them for non tw roms?

I am trying to save space by not having the cm version then the pa version and then whatever other version some rom says I need.

What I would like to do is keep a set of the different packages of the pa gapps and the pa ota update app so I can just install the gapps and the app and if an update is available then the ota app will just take care of it.
