SteamScore?

astats?

wastedonsteam got improved since I last used it

Raptr <- requires client for secret xbox / Live achievements, steam achievements can be tracked through the website in the user panel, listed as "sync steam achievements", if you're using the client to track PC gametime, achievement tracking is almost instant when you exit the game.
Astats <- nothing needed aside for your steam account, obviously.
Giant Bomb<- kinda slow with updating
Playfire <- extremely slow fetching achievements
Evolve <- account can be added and achievements will get crawled at a set interval, kinda like Astats, Giant Bomb & Playfire do.
Oh and Metagamerscore, but you already knew about that :p

Steam Achievement Hunters was just fucking awesome, I'd say the layout was pretty nice and functional (especially compared to other sites like this) and site had most of the useful features I could think of, like easy tracking your friends and their progress or walkthroughs. But what I realised just after it ceased to exist, the best feature was no problems syncing my account, before SPAH I used Astats but it never fully showed my achievement list and all games. Never. And it still doesn't. Just like the rest I tried after SPAH went down...

I really don't like how Metagamerscore looks, not just that it tracks non-Steam achievements (booo) when all I care are Steam ones and I'd like to be able to see comparison between other Steam users and just their (or mine) Steam achievements.

Besides, SPAH had it's own achievements for doing stuff... achievementception!

If cg just could see our potential and expand his empire to a service tracking achievements... Achievement whores of all countries, unite!

Bump:

Anyone fancy joining the Steam Gifts Achievement Hunters crew on MetaGamerScore?
Passphrase is "thanksforskyrim" ;)

I mainly use SteamScore but it fails to update half the time. WastedOnSteam reports my stats incorrectly as they've duplicated quite a lot of my games :S, Playfire tracking has never worked for me, and though it's the most accurate one I've tried, I can't deal with how ugly Raptr is.

Will take a look at MetaGamerScore and join the crew, thanks Adam!

EDIT: Messaged WOS's team and they fixed the error, so they're my top choice at the moment :)

Raptr works but gets irritating

Yay. joined Steam Gifts Achievement Hunters

Hunting achievements can be fun, I joined the crew too.

I am in as well. :D

There's playfire :)

Hmmm, I used to complete trophy lists in PS3 games. Steam achievements I never really complete although they still influence me buying a game lol.

None the less, I will join you on MetaGamer!

EDIT: Oh, trophies count as well! Great!

Hooah! Oh wait, I'm lowest scored... Shame, been a PC gamer on long time, but playing on Steam (legit) just for a year.

RAPTR

Joined! :P

I mostly use astats and SteamScore. SteamScore is nice just because you can quickly look at what you have 100% and what you're close to 100%ing. The mod(s) at astats do a good job at keeping up on cheaters and checking/verifying information posted in the cheating thread, or at least they were last time I checked.

I prefer Astats over all of them,it doesn't have the prettiest layout, but it seems to be have the best support and shows a lot of information I'd like to see on the profile.

The only other site I use is sAPI which isn't for achievement tracking, but just for the random stats they display. They also have a neat feature that keeps a list of your games and displays any that you've lost which is useful if you trade and are weary about people charging back on keys they've traded to you.
