360 Serpentine conversion - March Performance vs CVF Racing

I am looking to convert to a serpentine system on my LA 360 build ( I already have to purchase a couple brackets and pulleys - car will be a street bruiser about 400hp to wheels)

Doing research, March Performance seems to be the number choice with CVF Racing popping up. Anything other

Looking at March 40-400-8 and CVF B-360-SERPENTINE-ALT

Differences - March costs about $50 more

CVF - includes and altfan and uses 8 rib belts

Anyone with experience with either? Or should I stay with vbelts
