Sigma + Sony primes or LA-EA2 + Minolta AF primes?

I just left the Nikon camp and got a C3. The kit 18-55 is OK but I really grew to like the Nikkor 35 1.8, and shooting with primes in general. I basically want an under 20mm, a 30-40mm, and a 50-60mm.

What would yield better IQ: Sigma 19mm 2.8 + Sigma 30 2.8 + Sony SEL50F18, or LA-EA2 + Minolta 24mm 2.8 + Minolta 50 1.7 + Raynox HD-6600 Pro .66x wide angle converter (which would get me a 16mm, 24mm, 33mm and 50mm)? The costs come out about the same, the speed is about the same, etc...

Would the E-mount setup have better ergos? That might be the difference.
