As others have chimed in, BMW uses the phrase mixed performance tires for high performance summer staggered front and rear tire sizes. BMW has only offered all season tires in a square (same size front and rear) setup.
As far as selecting between the two wheel options:
1. 747 are unique to M50i, the cerium finish looks nice when clean but it's a lot of work to maintain - I have similar wheel finish on my M550i but ceramic coated to make it easier to clean.
2. 742 are fairly common in my area - they're nice but not my a/ - I do like the distinctive design.
