sentinel will receive great benefit, it doesn't need sig stones. although, it's a generic AG. if there are other champions you don't have yet that need to be awaken to be good, you should wait. examples: void, cap iw, starlord
Hold for omega, aegon and void ... but if you want to use it now, Venon the Duck and Sentinel are the best out of the list, but they do not get that much from being awaken.

These champs are fine without sig ability
