I'm pretty sure all 3 cities leves give the same amount of base SP, the only real factors is how quickly you can raise it to 4+ stars and how quickly you can complete them.

Also is 7988 SP with Aspect? Its misleading saying that then too... since that would be 5300 SP or so before Aspect (btw there is a Faction leve in Coerthas that gives 6000 SP, or 9000 with aspect).

I think we should start to say why certain places are better than each other (under the assumption that all 3 cities leves give the same base SP, which I think they do).

Pros:
Limsa
- ~70% of leves cab be completed in 4 minutes
- Has Efts (efts are easier than Pieste/Toad... die faster)
- Objectives are medium range from the node.
- Leves are typically in no-agro mob locations

Grid
- ??? (I haven't done Grid yet)

Uldah
- ~50-70% of the leves can be completed in 4 minutes or less.
- Leve destinations are typically close to the nodes.
- No defend the node leves

Cons:
Limsa:
-Has 3 or 4 leves with Mongrels, which are typically higher level than other mob types and hard to kill (HP drain)
-Has 4 defense leves (you cannot typically get speed SP bonus on these leve types, tho they do have a lot of mobs to kill)

Grid
-Some leves are lots of Toads

Uldah
-Has Pieste+Toad combo, no Efts
-Lots of Mongrel leves
-Lots of agro mobs around leves (BW)
