I still maintain that Patton was too "subtle" to break out too much beyond the "niche market" he was in, at least here in the U.S. He didn't display blatantly dazzling chops like Smith, his repertoire was nowhere near as blatantly "funky" as somebody like Billy Larkin, & he made few, if any, concessions to "commerciality".
Sure, he was "greasy". But his was a most organic form of grease, & it didn't necessarily call attention to itself unless you were predisposed to hearing it. I myself had the first few BN albums (at a time when I was more about the "uncompromising sounds of freedom" and all that stuff), and was basically underwhelmed until I got Accent On The Blues & Understanding. Then I went back & re-heard what I had missed the first time around. I suspect that my experience of not fully "getting it" was not all that uncommon.
There's a big difference between cats like Patton & Roach and people like Smith & Patterson. With the latter group, it's all there for you, you can't miss it. With the former group, it's not so easy, unless, like I said, you're predisposed to where they were coming from in the first place (and perhaps tellingly, I discovered Roach after my Patton conversion, and "got" him immediately).
What (almost?) all those "hits" have in common is a strong beat, a beat aimed at the feet of dancers. Either that, or a level of overt emotionalism that hits you upside the head. Or both. Big John wasn't ever about any of that, and that's why I think he didn't have the big breakout tune.
But we all love him now, so hey.
