Well if we are not taking Michael Kirkbride's Posts as gospel The Altmer all want to return to Aetherius, anything other than unmaking mundus doesn't make sense.
Alrighty, serious answer time.
1. Bosmer
Carnivorus elves who say fuck you to woodland elf sterotypes and who can turn themselves into beasts to unleash hell upon their enemies? Yes please.
2. Orsinmer
A close-second place to the elves who are not much like elves and are the best smiths in Tamriel
3. Dunmer
"You n'wah!"
4. Maormer
After seeing these guys in ESO, I wish we saw them in Skyrim. So different from our current elf roster and very cool-looking.
5. Altmer (and Ancient Aldmer)
Starting to get into the tied-range here because I do find the Altmeri culture and Thalmor fascinating.
6. Dwemer
Science. That is all
7. Ayelids
Super interesting culture, shame I don't know very much about them
8. Chimer
One of my least-favourite, nothing more then typical Fantasy elves.
9. Left-Handed Elves
Extinct but interesting enough due to theior influence on Redguard culture.
10. Falmer
Last on my list merely because their near-extinction and their current state is quite sad, similar to the LH Elves above. I do like them but I cannot see anyway they will be able to become sentient once more
