I remember awhile ago, that Rowland the Bastard said if any record does not have a 303 in it, then it's just techno. The reason behind that is, every Techno/Acid Techno producer in the True Love Collective, already have labels that can be called 100% ACID Techno. Then there are labels like Hydraulix, RAW, Powertools, Max/Min, No Entry, Cluster, Super Conductor, and 4x4 all which have no 303's in them, so those labels can be labeled a different genre.
There are so many great acid techno labels out there, and it's also great that they've made labels that make hard, stomping techno. Because I've spun a set with 100% 303 laced records, and the acid lines can get played out after awhile.
