I agree. In general we could argue endlessly about the pros and cons of every TP, but as the whole picture I found a minor skew towards the Karavan.But in general, from my experience, things are fairly equal with perhaps a very minor skew towards Karavan.
Interestingly, I found this was caused by the fact that the Karavan-lands (forest & lakes) have far more aggro and less good hunting spots than the Kami-Lands (desert & jungle).
The TPs generally follow the pattern that in the Kami-lands, Kami TPs are very central in the region and Kara TPs are on the outskirts of regions. In Karavan-lands, the Karavan TPs are central and the Kami TPs are on the outskirts.
So this should balance out, except that the Karavan-lands are full of aggro so the outskirt Kami TPs are often behind walls of aggros (UB, HH, Fount, Loria). While in the safer Kami-lands, having an outskirt Karavan TP is actually preferable because it puts you right on the best hunting spot (GoU, Void, SC).
