No, you probably wouldn't.  What 16 bit gives you is editing headroom.   
When you apply curves, levels, or any tonal adjustment, you end up 
getting rid of lots of gray tones, which leads to posterization and 
spikey histograms. 16 bit has so many that even extreme adjustments 
leave plenty of tones.  So, if you're not doing much editing, 8-bit is 
fine.  If you are, or might, do some tonal editing, 16 bit is the way to go.
