There is a wide variety of finishing methods which seem to be personal prefernces. The most critical portion of the knot strength is the FG portion (the wraps). That 'chinese fingertrap' portion must be cinched down super tight to actually bite into the leader material. After that, the finishing is more for building a transiton point for when the knot hits a guide. I like the rizutto because it builds a small cone-like ramp for the knot. Knock on wood - no FG failures so far.
For me, I tie the FG wraps, place a single half hitch (mostly as a temporary holder), then do the Rizzuto whip finish. The key is to tighten the main line braid to leader portion first; before tightening the Rizzuto. Recently, I've started doing a partial cinch after the FG wraps and my half hitch. After that initial cinch, I complete the rizutto. Now when I do my final cinching process, I see more if not all the braid wraps slightly shift color indicating the knot is fully locking in.
