I pretty much use them. I'd recommend just sticking with the first algorithm for blinker since it's much easier to learn. I still can't do the second one faster than the first one, though many other people can. If you are going to use the PDF for the 2-look PLL from the Badmephisto page, I would definitely switch the first two algorithms from CW Corner Cycle to the T-perm and the E-Perm to the Y-Perm. I would also switch the Z-Perm algorithm unless you are already good with M slices.
