Yes, both though CF in only spot duty. It is easier to get reads on balls in CF from personal experience. Expectation is CF is better defender because better players play CF due to it having more opportunities to make plays in gap. Granted: Experience isn't MLB experience so not really relevant.
So I googled to see what an MLB player had to say about subject to see if I was missing something due to harder hit balls to the OF in majors. First link had a detailed description of the different OF positions from Kevin Russo who had a cup of coffee with Yankees. Oddly, he talks about OF positions that same way I do except the differences between right and left. Left field is the most difficult position in the outfield. The balls that are pulled by right handed hitters can be much more difficult than the balls pulled by left handers you’ll get when playing right field. Righties will hit any type of ball to left field (hook, topspin, or slice). Balls hit from lefties that are hit high in the air will work back toward the field or leftcenter gap, just a little bit. The lower the baseball is hit from a lefty the more slice it will have off the bat. Centerfield. When you play center field you have the best view and can get the quickest read off the bat. Reading spin off the bat is much easier in center. This is the easiest position in the outfield. Right field. Lefties will a hit more true back spin to the pull side than right handed hitters. Right handers will slice balls most of the time to right field.
Just an add in. I read somewhere, possibly on this forum, that Right field was important for arm because you are never going to make a throw from LF to first to get someone out, but RF to third would happen. So 2 equal defensive guys, the stronger arm goes in RF.
