I was an early adopter to the Pens and had them all. Then came the EM5 with which I never bonded because of its ergonomics and over designed menu system. The GX7 is, except for the G1, my first Panasonic, and the best mft body as far as I am concerned. I tried the Em-1 and whilst it is an impressive tool, its DSLR gestalt does feel oversized for the small sensor and for what mft should be all about imho. MFT should take advantage of the small sensor footprint and the resulting compact lens sizes. The EM 1 goes into another direction, bigger heavier, overpriced, trying to be everything to all people. IQ wise, the EM5, EP5, GX7 and EM1 are neck to neck. But the rangefinder inspired styling of the Panasonic wins for me and if the EP6 has an integrated EVF I might buy Olympus again.
