Apex Vtec Controller Vs. SAFC

Just a quick question on this. But is it true that a Apex SAFC does the air to fuel ratio timing and delievery AS WELL AS changing the point of VTEC? Would it be more beneficial to just get a SAFC because it adjusts fuel/air ratios and modifying your VTEC point, versus a regular VTEC Controller?

No it doesnt do both unless you have the V-AFC, which does both.
