There are several equalization techniques:
1) "Valsalva": pinch and blow
2) "Toynbee": pinch and swallow
3) "Lowry": holding nose, closing mouth, small pressurization, and a swallow
4) "Frenzel" (or "Marcante - Odaglia"): diaphragmatic
5) "Frenzel-Fattah mouth fill"
6) "Hands-free": voluntary opening of Eustachian tubes
7) Other

In scuba perhaps technique is less important than in freediving. As long as you equalize, it's done. Anyway do you think there is a best way to equalize? Is it really important to choose an efficient equalizing maneuver or actually in scuba any of them will do the job and the advantage of using a proper technique is negligible in terms of air consumption?
EDIT
I changed the list and added a short description of each maneuver
