I have a MDT XRS, great chassis, put an Arca rail on it, nothing else needed. I like the rubber grip texture on it, and the fact it's swappable if I needed to change it out. It came with spacers to adjust the length of pull as well.
Someone I shoot with often has a KRG Bravo. It's nice, but the grip isn't swappable (part of the molded plastic), and they had to buy spacers to get their length of pull right (they have the 10/22 version). I think they had to buy something else for that chassis too, but not sure.
Point being, both are good. You won't go wrong with either, but you might consider the XRS as well.
