Remington picatinny scope rail???

Depends what's more important to you...

steel is stronger and heavier, usually more expensive
aluminum is, well, not those things.

How much different those things are from each other really just depends on brand and (more importantly I think) how you treat it. What are you planning to use the rifle for?
 
I like the steel one NightForce builds. It is a good compromise of strength and light weight. Aluminum is too flimsy and some other makers steel ones are much heavier. To save weight I use Leupold Mark 4 aluminum rings.
 
Some of the steel rails I have seen are excessively heavy, good to hear the NF is a good compromise on strength and weight. I agree with the use of alloy rings.

Are there any alloy rails that are hard coated?
