Solodallas >> ownwhammer >> all
no way.
I'm not saying that every OH is golden but there are so many fantastic Ownhammer offerings they are still the reigning king and they are the bar by which all other IRs are measured IMO.
Solodallas does have some gems like their G12-65 so don't get me wrong.
After seeing so many companies do IRs, I find it hard not to find a good IR made by anyone. There is always something in any pack that would work for me. Like I said there are many individual IR files out there that I may prefer to OH but if I was forced to use one vendor it would be OH.
The PR25, PR20, GNR25, GNR75, ORNG, MAR66, RECTO STD, EDVH, DZL-RL, m55, h55, h75, v60, v70, BB1, the Green Vintage pack, the Rockbox, the Essentials., VVRB E130, MAR-CB V30 and M20, MAR-TV.... all quality.
I prefer OH over York for almost anything but they also have some great stuff. The BGNR, MES 212, ZILLA stuff is very good.
Having said that, as I look at my most used presets I'm currently running these:
