Depending on how the 4:3 video is shot, if you crop it to 16:9 you might get heads chopped off...

I was just watching Michael Jackson - Live in Bucharest on tv tonight. It was shot in 1992 and in 4:3. Some idiot decided to convert it to 16:9 by cropping the top and bottom off the video. The picture quality looked poor and often you'd see Michael dancing without a head. lol.

Anyway, there's no correct answer - just personal preferences. You're in a good position as you have 2 angles, so you can always switch to the other camera if one shot is negatively affected by a crop.
