It still puts in NOC, and actually seems to have higher damage potential than the 5C j.B j.C 2D combo at the cost of a bit more Nirvana life (and harder to execute, but if you learned optimal combos in CS1, you should already have some muscle memory for it)
Example combo: 5B 6B 623C 22D 5C volante 236A j.2C allecan sj.2C j.C 2D backdash j.2C allecan 5C j.C 4D backdash 5C sj.B j.2C j.B dj.B j.C 8D j.2C allegretto 8D
damage: ~4500, meter gain: ~70, uses about 1000 more Nirvana life than other 5B combos
EDIT: Forgot to include information on Nirvana gauge changes (and will also edit the OP with this)
Note: this is all estimated from tests in training mode and may not be 100% accurate.
8D, 6D, 4D, 623D all cost 600
2D, 3D, 421D, 41236D all cost 720
22D costs 500
214214D costs 1000
236236D costs 1500
Continuation costs all seem to be about 140-150%, except for 22D, 214214D, and 236236D which are all 100% like before.
