Humans, even in the real world, tend to pick their favorites over all others. Lilith, Lucifer, Asmodeus, Belil, Astaroth, etc., etc., etc. all had their own cults. Some, creepily, still do to this day, but it is what it is. Typically such cults are tiny or just very well hidden and not fully understood by outsiders. Secret societies sometimes pay lip service to this specific devil or that, but mostly they're just edgelords hanging out and using it as an excuse to play black metal and get trashed.
