I must say that I completely disagree. In the history of competitive 3BLD, 3OP has actually been proven to be fast enough for WR-times even long after OP and M2 appeared. I'm not even talking about the Caltech era when sub-2 was a big deal; I'm talking about consistent sub-1 times with 3OP/M2, most notably achieved by Alex Yu, Rafał Guzewicz, Tim Sun, etc., which is still considered (relatively) fast today.
OP, on the other hand, has never ever come close to being a WR method. As far as I know, only people with (way) above average tps have been known to achieve consistent sub-1 solves with OP (Cornelius Dieckmann, I think?) And all this is happening with a lot more people using OP than 3OP. Pretty much no one learns 3OP anymore.
For as long as I've been cubing, just about the only merit OP has over 3OP that I've heard is the learning curve, never the speed.

My bad. I for some reason thought OP and BH showed up around the same time, and that's why it was never used for WRs.
