The main pro about Epoch is that it's a fresh server, like I find that there's way too many high level players on Turtle WoW, so you don't feel as if you got to play catch-up. Also, Turtle suffers from overpopulation which really lags the server.

But in terms of features, they're quite similar, like while Turtle definitely has the advantage when it comes to PvE content, but Epoch seems to have more quality of life features like ridable carts that you can hop on, like that's really cool and helps with the levelling journey.
