The FFB is certainly better in DR1, and certain things in 2.0 are better too such as the physics of the mid engined cars (those that were poor like the 037 and a few others), the feel on asphalt is better, and on gravel for me a bit worse, the rallycross is much improved.
But for me the game is not as good, it is close. But a step back, looks prettier, but it seems they want to push heavy rain on you at every chance which is boring and in some cars undriveable and simply not much fun, stages are not as flowing as before, they seem to be either very tight, or very fast and narrow.
I would get it on sale yes, the DLC model is pathetic, basically offering pretty much all DR1 content for a paid amount, yes there is new stuff but that alone is not worth it. But if you get a deal for say game and seasons 1 and 2 for 20 quid, it's worth it.
Just don't expect it to blow you away immersion wise as DR1 did for me.
