The three motherboards won't make much of a difference since the R5 2600 has low TDP and low power usage. The VRM performance gap will be almost nonexistent. Just pick the most affordable or your favorite and stop there. As I mentioned, none are particularly bad—they all perform similarly on the motherboard tier scale. I’d recommend Asus or ASRock.
The heatsink offers a large surface area and the TUF Pro would come in close behind in terms of VRMs. You can choose based on appearance or BIOS compatibility—it won’t cause any problems for an R5 2600.
