Should I swing or hit?

[teach]

I am 57 years old, 5'8" tall, and tip the scales at 140 pounds. I am not strong. Unfortunately, I'm not flexible either. My original sports were baseball, and then tennis for 20 years. Would my physical non-attributes and background suggest that I try to become a hitter or a swinger? Or, would this be more a function of which motion I find more comfortable?
For those who might suggest that I learn both motions, I'm a
hacker. I'll be happy if I can learn *one* of the two swings!

Thank you in advance for your advice.
