from my limited Sony product knowledge the A99 would be the best all-rounder. Coupled with dual card slot and weather seal.
I did some reading on A7 series weather protection, seems like it's quite limited in that aspect.
Not sure if the A7S is any different than the A7/A7R in terms of protection, although the A7S has a metal mount while the A7/A7R don't. I have used the A7S in moderate to heavy rain for 20 minutes. After that the rear dial started jumping. (Thus making one shot at 1/1250s when I didn't need it!) 1.5 hours later though it seemed to be okay again. When I returned home I put it in the dry box.
I also brought my A99 out for one time I thought I'd need the 24 megapixels, and even on the street in daylight I was thinking I needed faster shutter speeds (I'm usually on Aperture Priority with Auto ISO 200-6400 on the A99). However on the A7S I can safely be on Manual Exposure, F4.0 1/160s, Auto ISO 200-409600 - 1/160s is fast enough that I'm unlikely to get blown highlights in daylight.)
I guess you could say the A99 is an all-rounder, though just not in the ISO aspect - but then, nobody else is near the A7S. The dual card slot thing is something I have to think hard on how to use. I've copied folders from one card to another, but this doesn't work once your second photographer is using a different system and shooting RAW only. (I didn't check if it would copy anyway even though it saw no pictures.) As for weather sealing - I guess I don't quite enjoy shooting in the rain for too long!
So by far my A7S is still my daily driver - and it will be for event coverage, too - with the A99 only for studio work. (Next time I get caught in the rain, I'll just disable the affected dial and save settings to the 1 or 2 memory settings slot on the mode dial - not memory card slot heh.)
