Is it better to plan an "bad" first face?
I think the Algs for the last step are shorter the less of the sides are solved after OLL
With Ortega I prefer to not have a solved fist layer and end up with a T-Perm or Y-Perm.
But in the moment I'm not so far to plan things like this. I usually use the side that is easiest to solve.
What i mean:
If you have a full first layer, you can get these Cases (with the Algs I use)
Adj (T-Perm); y2 R' F R' F2 R U' R' F2 R2 (9 Turns, even more with 3x3 T-Perm Alg)
Opp (Y-Perm): R U' R' U' F2 U' R U R' D R2 (11 Turns, , even more with 3x3 Y-Perm Alg)
If you have one bar in the first layer you can get these:
Adj-Adj (2 bars): R2 U' B2 U2 R2 U' R2 (7 Turns)
Adj-Opp (1 bar): R U' R F2 R' U R'
(7 Turns)
If you have no Bars in the first layer you can get these:
Adj-Opp (1 bar): R U' R F2 R' U R'
(7 Turns)
Opp-Opp (No bar): R2 F2 R2 (3 Turns)
So it's better to have no Bars or even a full layer if you solve the first layer
There is one exeption: There are no chances for a skip this way.
Maybe this compensates the advantage of the shorter algs because this is the shortest
