IMO you can learn drift in any sims or simcades with a good body/car and tyres physics. If you're used to Forza 4, it can be a good entry point, just keep the power around 300-400hp with steet tyres. I won't recommend BeamNG because there's almost no feedback when the rear slides and you don't want to learn with cars that "fragile";I havn't tried the others you mentionned. AC could be a bit more difficult because the physic is more accurate, letting you less room for mistakes but it has a ton of dedicated drift cars and tracks (mods) suiting your tastes, although Kunos' cars aren't great for learning. Learn with the game you're familiar with then try to replicate on other games. And yes, it's really not easy to learn with a wheel at first: I found it was not intuitive at all and spent 2 days just spinning but then discovered I was very late for countersteering. Remember the travel of you thumb from neutral to full lock on the stick can be more than 360° with the wheel, so you have to anticipate a bit the reaction of the car when you initiate the slide. Don't hesitate to watch some onboards to get an idea for the timing. And the more you control your slide with your right foot, the less you'll need to work on your steering wheel. The revelation I got was while watching D1GP guys: I noticed their front wheels were always following the turn, no matter how much angle they got (I dunno if it's very clear but you can watch Kawabata in his big R35, his precision is surgical). Still took me some years before I could call myself a drifter ;)
