i geeked out on clay early because of the power… but it also falls down on overall enterprise enrichment layer….. this is where Scalestack excels
if you just need a smple import tool it is too much but if you just want things to work for enrichment at “scale”… check out “Scalestack” as alternative to ALL of the tools you listed above
