Well, if you look at it Salafi trends, they usually speak worse of Deobandis than Brelwis and extreme Sufis. For example, if you look at a lot of Salafi websites, their "refutations" sections will have many articles on Deobandis and (particularly) Tableeghis, but very few (if any) articles on Brelwis. I think this has to do with the fact that Salafis (the disingenuous ones) are more threatened by Deobandis, due to the truth they speak, than the deviant Sufis, because most of their claims are ridiculous to the point that warning against them often isn't even needed.
