i13's Super real is a morph bundle of thel morph sets.

i13 Real Details, i13 Real Breast, i13 Real Smile, i13 Real Bite, Real Pucker, Real Belly, Real Rolls

Boom Lip System doesn't make RealBite or RealPucker uncessessary - they are different morph sets.  Studio expression is another set of facial morphs.  The Expression Studio is a collection of facial expressions, not morphs.

They all do different things.  I tend to mix and match these on my V4s.

All of these can co-exist with Perfect V4 - Perfect V4 is designed to fix flaws with the basic mesh.  i13 also has something similar - the OVERHAUL system.  I have both.  I have found it to be 6 of one, a half dozen of the other.  On the other hand i13 also did an M4 version of Overhaul, which I use extensively.
