PCMS seems good.
Roux is a perfect example of how trying to crowbar PLL into a method isn't always a good idea.
I looked at a bunch of methods before, and saw this one as one similar to Roux, like Corners First.
I'm no Roux expert (I don't use it), but I think Roux is definitely better.
Some D edges in Roux can be eliminated during inspection, making look ahead much easier, and then only 2 D edges will remain unsolved the rest of the time, but you see them while doing M turns anyway.
In columns first, after making the columns, not only is it harder to look ahead during the 4 pairs because of D edges, you'll have to return to the D layer after making the columns. Plus, it seems to take a little more thinking since it has so many steps.
And with CFOP, D edges are all completed during F2L, and OLL and PLL have extremely fast easy recognition and execution.
Overall, CFOP is just less intuitive, and what's great about that is the only improvised part (the cross) is thought up during inspection.
I love how you're all focusing on the order of steps and other silly things that hardly make a difference when the real problem is the movegroups being used.
Look at ZZRoux or FridrichRoux - there are quadrillions of step configurations that all basically amount to the same quality of system.
Oh of course it's not the biggest issue. Nor does it 'hardly make any difference'. Don't get me wrong, all I'm saying is it does make a significant difference.
As for thinking up a way to reorder, I can probably think of a different example where it does matter. Just here the move group is quite a big problem and is awkward no matter where you put it. Or why not just not do it...? We could do something else maybe that's easier...
Edit: why not build 1x1x3 blocks then CLL then solve remaining columns? I find that faster and I did that in my 20sub20 vid. This is an example of re ordering which may be helpful

Regardless of its practicality, I would like to see someone dedicate a couple years with it and see how far they get.
