Yes, for a brief period we did powerbacks on the 737-200. I didn't like doing them, too much potential for mistakes. Lots of noise for little push. I have always thought reverse power is not very effective in relation to noise and vibration produced. Now most airports in Europe restrict to idle reverse anyway. Autobrake is the effective way to slow down, and you can select what degree you want. Guys that use manual brakes start punishing them on one side only- that matters on a hot day with no wind and short flights.
