Purely on what I've observed over the last 10 years.
Mares: Great Masks, awesome Fins (I have 2 pairs) but: BCD's that will leak as soon as you look at them and lemming-like weight pockets that will hurl themselves from your BCD as you giant stride.
APEKS: Great Regs and decent Wings
Scubapro: Functional Regs and they make the best semi-dry going (The Nova Scotia)
Tigullio: Um
SeacSub: Well...
Cressi: Good Masks
Aqualung: Bomb-proof basic regs (Titan/Calypso) great top-end regs (Legend) and the old style Wave BCD is still one of my best purchases.
