Fujifilm Xpro-1 + 35/1.4 + 18/2.0 + 60/2.4 vs Canon 6D + 50/1.4 + 28/1.8 + 85/1.8

The Fuji-X is a APS-C RF while Canon 6D is a FF DSLR. Each of the two setup costs about $3200.

Anyone has experiences on the IQ of the two systems? which system has more room to expand? I'm asking the experiences in real usage, not just the impression after tried in the camera store.

I'm sure there will be a lot more room in my camera bag for Fuji-X than for Canon-6D, but I'm talking about expansion in terms of system usage and adaptability.
