Meduli is kind of a shitshow. It's grown a lot from like the second ghetto beside Tindrem, though. The plus of Duli is you have KoTo there and OG, tho they too often seemed to be trying to mounted zerg the GY to go after pkers haha. It's a tough choice, though, it depends on your play style:
Bakti is friendly, as said, and you can get all the Khurite exclusive books, riding, MA. You can also get almost all of the books you could get in Meduli if you can safely make it to Jungle Camp. If you are gonna be extracting, I would start in Meduli, sab gives out more worth stuff raw than Gran, you're gonna need Sab powder eventually, and extraction books are there, plus stuff like Heavy Armor Training and Feint.
One missing book is JADEITE lore, which is a key extract from Saburra, so you'll have to slide over somewhere else to get that (unless they changed it??)
I'll probably spawn into Duli once all this server stuff calms down. Probably still gonna home base Bakti tho, cuz dems my peoples, even if I don't know most of the new dudes haha.
