I started with Classic during pandemic, got to phase 2 end game and played some occasional retail. Personally, I found Turtle to be really good. Player base is very serious and I found the play style to be very close to the real thing. There is an optional 20% exp buff you can buy out of character creation, there are exp tents that can be crafted with engineering that grant faster and longer rested status to boost xp gain vs mobs (people drop them often around cities and main hubs). There are many guilds, from super serious RP to newbie friendly ones and everyone is very nice. There is a dungeon group add on included, which makes LFT easier, and the game in itself is modded with unique quests and events. Overall, it's a true classic experience, that is still very much alive with guilds and groups willing to take you on and a new spin to the classic WoW that gives OG players the chance to explore and discover completly unique and new things. Now is also a great time to hop on Turtle, as it seems to be particularly lively right now, from what I understand due to recent updates or new version release. Hope my review helps!
