The answer to all questions of moderate or greater complexity is, “It depends.”

Which one do you *like* better?

For me, it’s a no-brainer. An image I have is sharper than one I think I can 
get by spending more money.

I’m happy as a clam with my OM-D. I don’t want to carry FF.

Simple physics dictates that IBIS cannot be as good with FF than 4/3rds, too. 
So add a tripod to the mix, if you REALLY want to get the most sharpness out of 
FF. If want the ultimate sharpness, the old 1/f rule doesn’t work for 
hand-holding; you need at least two to four times as fast an exposure. So the 
sharpness you get hand-held at 200mm with 4/3rds can only be had hand-held at 
50mm with FF.

I don’t want to carry a tripod in order to shoot tack-sharp images at 1/8th. I 
don’t care if FF is theoretically capable of more sharpness, if you have to use 
a tripod to get said sharpness.

For 90% of my photography, my tripod is either a copy stand, or a motorized 
equatorial mount.

(For shot-to-shot consistency, I’m using a tripod for product photography for 
websites, but WHO CARES about minor sharpness differences when the image will 
be 256 pixels wide? A photo of soap in a box is not going to be blown up to 36” 
and shown in a gallery. :-)

Here’s some soap for you, to wash that evil “specmanship” taste out of your 
mouth. (BTW: this shot is not possible in 4/3rds, which has too much DOF for 
such things... :-)
