IMHO it depends on what you want I break them down to two types side airflow (Bellus) vs Bottom Airflow .. the similarity between types is very great the different between lets use a Billow 2 or a Griffin vs a Bellus is much greater it depends on what you want.. Better as in build deck? Airflow which directly affects everything...
I myself have most of them and I prefer side airflow best is subjective but based on type is more accurate
