Another vote for wowace.

but to the original author, you say:
"For you Ace advocates, I should mention the Ace addon system, which many players choose because Ace addons play well with each other and used shared libraries to minimize memory use."

You've got it all wrong - people don't love WowAce because of the libraries, or the memory usage. People love it because the updater ROCKS.

I'm an addon-junkie, and tried tons of addons.
The biggest headache is not installing them, but keeping them up to date. The WowAceUpdater is MILES ahead of anything else out there.

In fact, I'd rather have a less-functionality addon from WowAce than a more-functionality addon from somewhere else. The ease of managing, installing, updating, and removing addons with the WoWAce addon is just so much easier than doing it manually, or with the other tools.

I have 55 addons that I use through WoWAce.
How do I keep them up to date?

-Launch the updater
-Hit F10



So, it's got to be a really compelling addon for me to go outside the WowAce family these days.

e.g. Auctioneer and Bongos.
