Yeah, but from my (admittedly limited) views into the "underground" most ROM distributions are still done in terms of GoodSets.
Which is why I asked the question. I am not a fan of the GoodTools at all (the name is a misnomer as far as I'm concerned), but it remains the "industry standard," so we have to deal with it. The GoodTools have the biggest databases out there as far as I know, but that's only because of all the bad dumps and hacks included with it (which most other DB's don't count). The larger number serves as a marketing advantage, which is why I don't think a competitor will ever overthrow the GoodTools unless it has a similar "unabridged" database.
