I can't see any of them, even S/ZZ/Phenex being a big upgrade over what's accessible for on an f2p basis at P0/T0. I ran purple funnels against Q before transcending and brought them up to the same experience in the raid event and other than the stun effect their performance was within 750 dps (not 750k, just 750) of each other at lvl 115 P0/T0 custom 10 and no unit enhancement.
