LFS is easily the right answer, anything after that is just plain wrong. Its honest simulation and the fact that you choose to drift with it is your choice, its not something thats coded into the game as a mode where they adjust grip/slip variables, its legit and it simply works because it works IRL too.
Im not remotely interested in drifting, but theres a decent community on there for it, cars to suit it, the option of free-roam tracks rather than having just 1 option around the track. Theres also demo access which is enough to try the drifting mode in the XRG around Blackwood on a drift server before needing to buy a license.
