The option list can go from NYC to SFC for all I care.
If I need to do prints at ~3' in size at 300dpi with out of camera images then there is nothing that Canon currently offers that will do that for me, irrespective of the lens. If I need clean shadows then there is nothing that from Canon that I can currently buy to give me that. And so on.
All the options in the world are meaningless to me if the system doesn't offer me the options that *I* need and what I need is better IQ, not a dozen super expensive and heavy lenses that I'll never own or use.
Conversely, the ability to capture the shots is just as integral to the process. I would imagine that for a very finite (miniscule) niche of photogs shooting very specific niche things, using Sony would be perfect and without issue. But for the rest of the real world (and majority of photographers), it is much more laborious and/or impossible to accomplish certain types of photography with a Sony a7xxx rig.
Not saying Sony won't get "there" at some point. I am hoping they do as I am more than willing to invest into a complete system with them as I have already attempted to do with the a7r/lens. Only problem is, they are not "there" now and won't be in the immediate future.
As it stands, I have way too many varying photographic needs and the Sony rig either makes it hard or impossible for me to cover most of those things.
And if you are one of the lucky few that is able to accomplish everything they need to with consistency and ease with a Sony a7xxx rig, then more power to ya. Also not sure why you would still be on this forum complaining since you should probably be on sonyalpharumors talking about your new Sony gear at this point.
