Our standard procedure here at our US airline is "flaps 5", "Landing Gear down, flaps 15, final descent checklist", "flaps 25", "flaps 30" (or 40).
We do use flaps 1 to maneuver down to 190KTS and flaps 5 to fly at 180. Flaps 10 are used when ATC assigns us 170 kts away from the field. Flaps 2 used to be used when we had the old block speeds but has shown to be of little to no value. I haven't used it in a few years now.
Hope this helps.
There are a lot of ways to "skin a cat" or fly an airplane.
