Community input on Icon Sets and gtk themes wanted

I am wondering two things:

1. What are your favorite Icons themes? Which do you use with Bodhi?
2. What are your prefered Gtk themes? And which Moksha Theme do you prefer to use it with.

I am wondering this because I would like to update our appcenter and or add more icons and gtk themes to our repo. I have never been satisfied with some of the icon set choices on our appcenter. A few of the icons sets listed there are broken in one way or another.

Over the years I have played with probably hundreds of icon sets and almost as many gtk themes. So I am wondering what are your favorites? To be added to the repo and or the Appcenter the icons set or gtk theme must be fairly complete and fully functional and work well in Bodhi. If it fits in well with a Moksha theme or another well known e17 theme that is a plus. I am less interested in how well it works with other DEs but if it supports the major ones that also is a plus.

For legal and philosophical reasons I am not going to add anything that is an obvious copyright violation and prefer FOSS licenses.

Thanks for any input.
