There are some interesting points. First, the Panasonic required a slower shutter speed at the same aperture, meaning there may be a difference in the way Olympus measures their f/stop and the way Panasonic does.

f/stop is I think pretty much a calculated thing rather than a measured thing. It's an fixed formula, not something that's up for debate. T-stop however can change for any given f-stop. I don't know the optical constructions of both but if for instance the oly had less elements it might have a slightly better comparative t-stop.

There seems to be very little difference in background blur, but there is a hair more with the Panasonic.

The Olympus lens was sharper at times, but not all the time. The Olympus lens did have better corner sharpness.

After reading this, I would choose whichever lens was cheaper, though you should note the Olympus lens is smaller and lighter.

The Olympus will work better on Olympus bodies if CA is a concern. It may be the reverse on Panasonic bodies.
