Oddly enough, despite the dozens of house rules we have had (and many we still use) in 5E, there is nothing that is my "favorite".

I surprise myself - me, a chronic houseruler - playing by pretty much by RAW (with the use of Feats and Multiclassing, if you consider their use as a houserule). Most game I DM however has a houserule or two specific to the genre and style for that game, or the players I play with.
