Reach feels much smoother than Halo 1 ever did. And sure, some mechanics are different than the original, but there is zero bloom (which I love). I think they made a good choice using Reach. I played today but then I reached the cR cap 
The only thing that needs changing is the jump height. It is waay to low! And gravity is waay to high!
It doesnt have zero bloom :l
Bloom is modified to around 85-80% or somewhere around there, but the misconception seems to be that there was no bloom before Reach. There was always bloom to an extent it just reset very quickly or had a very specific range of spread. You can tell because if there was no bloom then you could shoot a wall with an AR and not move and there would only be one bullet hole. 80% is closer to older halo spread. In Vanilla Reach its more pronounced than the Classic gametype.
