Air vs. magnetic vs. water rowers — which should I get?

Air rowers like the Concept2 RowErg use a flywheel that scales resistance to how hard you pull, which specialist rowing communities prefer for training fidelity. Magnetic rowers are quieter but cap out at lower intensities, and water rowers are praised for feel but are harder to maintain. Reviewers we read consistently recommend air for athletes who actually want to train, and magnetic for quiet apartment use.
