Nostalrius Begins - Quality wow vanilla realm (1.12)

.....I just want to know three things without rummaging through all that nonsense:

1. What's the best dps meter add on

2. What's the best Questfinder add on

3. What's the best threatmeter add on

As a bonus maybe your opinion on the best UI as well.

Vanilla Guide is honestly my favourite quest addon. When I'm not using it I find that locating quests to be a pain past level 35, i'll enter zones and find 1 or 2 quests max at quest hubs. This addon keeps you straight though, with it you'll find plenty quests that open up a plethora of other quests upon completion.

I'm terribad anyway so I need to use it.

Edit: Also with this guide, you'll find it tries to sway you away from doing the Elite/Group quests and if I remember correctly it doesn't take into account Dungeon quests. Those will be worth doing to make up for the grinding the guide includes.

3 different damage meters.

1. Recount - Simplest but ugliest, with the least amount of accuracy
2. Recap - Most complex but comprehensive
3. SWStats - Most accurate (when your whole raid is using the same version and synced up) and looks good

I haven't heard of this vanilla guide. Is it like the questhelper add on?

Rather than just pinpointing on the map where to go, it also provides written text (tips and such) by the author for each quest and he chooses the best/time-efficient quests for you to do.

Quest helper places markers on the map showing you where to go right? I haven't really used that.
