Default [Q] ROM vs. Vanilla Android w/ Xposed Framework?

Just curious as to what everybody's thoughts were about loading and keeping up to date with a ROM (pick your favorite lol) vs using xposed framework's various modules to re-create a lot of the funcitonality we have in ROMs.

Just wondering if anybody had any really good points to lean one way or the other or if it's more just personal preference

Cheers
