Tough call.
I would choose based on whichever bike feels better-in this case, Sram vs. Shimano shifting. I believe the Sram has adjustable reach, which may be a deal maker, and the lever and hood shape are different, as is the way the shift works. This is important, as the hoods/levers will get constant use unless you live on the tops or drops. I would rate the quality as about the same.

As for wheels, yes lighter wheels are noticeable on rides, being rotating weight which would make it feel like 3x more difference than it is. Less is much more on wheels.

So I would say, look again at the shifting, and choose which works out better for you as you will feel that every moment on the ride. You won't be looking at the bike then and the color won't make the hoods feel any better. If that's a toss-up, great, decide based on the wheels and color.
