I did not experience any FPS gain or loss between those settings, that I can remember. The FPS range was for Dragonsreach interior 61 to 103 FPS, Whiterun exterior 56 to 73 FPS and Exterior was 45 to 66 FPS. for the 1st, 2nd and 3rd runs not the 3 last test runs.
The only difference was the occasional micro stutter moments (multiple small stutter within a second) and freezes (moment where the image was frozen for say 1 second or so)
But those was (I think) not caused by how I had my ENB settings set but more because of the dynamic nature of the game/engine to load in different things in each runs making almost every run unique in some way or form. Different NPC bhevaiour and/or placement, different weathers, different script events and so on.
That is why I did multiple runs with the same settings and you can see that in some runs with the same settings I did experience either micro stutter or freezes.
I started at Dragons reach interior by the fireplace in the middle room and went through Whiterun exterior and followed the exact path all the way up to Helgen to the gate that you go through in the intro.
Did not experience a single CTD during any of the above runs.
And here are my ini file settings for both Skyrim and ENB, excluding ENB memory settings -
