Alright. I'll do this the best I can. The way I see it:

First Tier (budget bin)
Quando
Suzue Jr
Sovos

All are unsealed cup and cone. generally poor construction. Dust caps that shift/cones that loosen over time. BUT if you keep an everything and keep up on maintanence, they WILL last. no reason to just thrown them away right away. unless you are super non-mechanically inclined. Buy some cone wrenches and a tub of park grease and learn to love your hubs.

Second Tier (damn good, not the best)

Formula/Iro-----(Pretty much the standard street track hub. usually right around $200 a pair built up. Some Issues with the lockwasher breaking (get a new one for a buck and a shop. no big deal))

Miche-------(I've personally had an issue with the cones staying tight on mine. They liked to loosen (front and read). Also, the older ones came with alloy lockrings that are prone to stripping. You can get new Miche ones, or Campy lockrings from a shop. I liked them, but noticed no real difference between them and Formula hubs.)

Surly
Nashbar/Dimension
Kogswell
Dia-Compe--------(The company has been around for a while, but to the best of my knowledge these hubs are new to the market. at about $140 a pair, they're probably at the upper end of this tier, but I am totally unfamiliar with them, and they're sealed, so I'll put them here temporarily.)

These hubs are great for the plug and go riders. To the best of my knowledge these are all sealed cartridge (not sure about Kogswell) Riders that don't want to worry about their hubs too much, but are still looking to not spend an arm or leg will love these. I've used several of these hubs and have had no real or major problems with any of them. Great hubs for the money. Most of these are the go to hub for the introductory shopper. (mostly because these are the ones that come built up, but these are also great options for people building their own wheels, or as an introduction to wheelbuilding)

Third Tier (upper deck)

Phil
Paul----(use a non standard 44mm chainline. also, have heard some less than good things about these hubs. I know 3 messengers in philly that have trashed them, one of them is on his third set, so they seem to warranty them, though)
Level---(these are a little on the heavy side, but absolutely bulletproof. and have a genius cog mounting system. 45mm chainline. )
Suzue Pro-max (both sealed and not)
Campy Record
Dura-Ace
Suntour Superbe
Zipp
Mack
Royce---(apparently very good hubs, never heard of or seen them.)

The sealed hubs listed are amazing hubs (i've personally used Phil and sealed Pro-max) and love both of them. Spin forever and can be ridden year round with no worries. Best served for the messenger or the serious commuter (or someone that wants to impress people with how much they spent on their bikes) Someone that will not balk at sub freezing temperatures or heavy rain. That's where these hubs thrive. But the cost is great. They're certainly not cheap.

The non sealed options...Also great, but more for the track. Won't hold up well to street conditions, will need (or at least SHOULD BE) to be serviced fairly often to maintain performance. Serious low drag, but that comes with a serious lack of seals. Ride them hard. On the track. Or ride them when it's nice out. No reason to gritty up $400 wheels just to look cool.

***"standard" track chainline is 42mm. anything wider than that and you'll need a different bottom bracket, which length would be dependant on what kind of crank you run, and if it's road crank, whether the ring is on the inside or outside lip.

none of that was to attack anyone, just my personal input on the hubs in question. I've used a lot of those hubs, and i've never really hated a hub. Bontrager track hubs coming soon, if anyone wants it. I stuck with readily available hubs. Won't get into gipiemme, or suntour sprint, or goldex, or sunshine, or anything like that. Hope that helps some people.

EDIT: A point of contention on this forum. i know people that have had success for many years, and other with barely an hour. SUICIDE HUBS! If you are going to do it, don't ask if it's safe. Use a BUNCH of RED loctite. rotafix it on the hub very tightly. let sit. I would personally not go skidding around like crazy, or rely on it for panic stops. BUT, if you use a front brake for fast stops, My personal opinion on them is that they're fine. (people will disagree and that's fine). If you're going to run a suicide hub, just be aware of the risks, and don't complain if you get hurt or break it. That said. I'd use one, if i had a nice freewheel hub and needed a fixed wheel.
