Okay I want people to add to this based on their experiences. I'll put in 5 levels from cheap no name cr@p to boutique hand made beauties. Levels are based on Tone, quality of pickup and customer service.
I've not had loads of pickups so some of these are guesses based on what I've read to set the ball rolling:-
Level 1 - No compromise, hand made
BKP (obviously the top of level 1), Lollar, Fralin, Bulldog etc
Level 2 - High quality aftermarket pickups, mass produced rather than made to order
Seymour Duncan, Dimarzio, Fender Cusom Shop, TV jones etc
Level 3 - Good quality, far east production mid price
Tonerider, Gotoh (Add more here)
Level 4 - Stock Far east pickups on well know guitars
Epiphone, Squire, Wilkinson general cheap replacements
Level 5 - Turds. £7 off ebay for a fully wired strat guard from hong kong
No Brand name

Off course tone is subjective so you may prefer your level 5 Tele pickups to your level 1's. So it's just for fun.
And before anybody says largely pointless!
I would like to have every manufacturer on earth listed soon!!
