I think the best comb and brush really depends on your hair.

Personally, I just use my mixed Mason Pearson, no combs or anything else. Through trial and error, I've found this to be the best for my hair and my personality. True, a fine toothed comb (wide toothed combs just can't deal with the small knots of my hair) might be gentler, if used properly. But I have a tendency to detangle in the morning and night, when I really just want to be trough with it. So...a comb is not ideal for me. A brush is, because of user error when it comes to combs.

So that is also something to consider. You might have the best comb and brush combination in the world, but if they don't fit your way of taking care of your hair they will do you no good.
