Pro comp head failure

From high to low in quality and performance results. How would you rank, Indy, Thrickflow, Edelbrock and procomp / speedmaster?

Indy are the best if you get the cnc ported heads (360-2,360-1)

TrickFlow come cnc ported and max out at 300 cfm

Speedmaster is the old Procomp and flow a hair better than Edelbrock heads.
Speedmaster also come cnc ported but can’t match a TrickFlow head.
