Depends on your needs:
Assuming no manufacturing goofs - which we've seen in Holleys too...
A BG Mighty Demon would have these things if you're looking for them:
annular boosters
4 corner idle adjustment
idle -eze
threaded for replaceble bleeds and some restrictions.
Advantages would be for
an engine and fuel that prefers a smaller droplet size
an engine with poor vacuum at idle
Disadvantages IMO
almost certainly has high position IFRs
almost certainly has too many emulsion bleeds.
Both of the above can be fixed if you want and are common almost all newer billet carbs anyway.
