When you need 3-phases . . .
The additional hot leg gives you more options as far as cable run and load balancing is concerned.
A far as noise level goes, I don't know the db figures, but most "movie quiet" generators are pretty quiet. That said, they can be too loud at times. You may find yourself parking it around a corner and needing to run a good amount of cable. Depends a lot on the location.

Most (if not all?) 3 phase genies allow for voltage adjustments; weather it be in balancing small increments, or moving between 120v and 240v.
Also, on shoots where we were incapable of parking our genny far away, we'd build goal posts (speed rail across two Junior stands -- like tripe riser combos -- held by Big Ben / Cheeseboro clamps) and spring clamp several sound blankets to them.
Just be careful when using sound blankets not to cover the Gennie's vents.

0 db is silence
30 db is a whisper
40cb is a soft conversation
45-50 db is a conversation
55 is a loud conversation
60db is a loud radio
90 db is a lawnmower
110-120db is a jet
So I wouldn't want to record anywhere around 70db.
