In the end my sister got the E90 M3 with DCT. In all honesty she thought the C63 was too much car for her. She also thought the M3 look more feminine.

I take your points BetterMakeWay, but I think the bottom line is that high RPM and displacement are directly interchangeable replacements for one another as they are simply different means to the same net result. The other factor is that the M engines are actually very heavy. It often comes as a surprise to some to realize that the engine in say the M5 is actually heavier (by close to 90lbs) than the 7 liter LS7 engine in the Corvette. The reason is simple - the technology needed to allow and sustain the higher RPM in an M engine does carry a significant weight penalty. A larger engine that may be lighter, despite lower RPM, can be just as elegant a solution and just as effective as a means to the same end.

The other thing about the C63 is that, unlike most earlier AMG output, it was designed from the ground up to be the car it is rather than being a tuned version of the donor model. I really like both cars, and I think the M3 is an awesome, but the powerplant in the AMG would be the reason I'd go for the C63 over the M3. Bigger displacement doesn't necessarily carry any penalty whatsoever in terms of the size or weight of the powerplant, but without forced induction you'll never see AMG-like levels of torque in an M engine.

I would need to test drive the C63 (and the M3s) before making a full opinion but I think I'd prefer the M3. In styling, all 3 are nice with the E92 M3 tops, with the E90 M3 too subtle, and the C63 a bit too agressive. I do like the 3 series interior but only in 2 tone with all black being too plain.

I would salvate over the C63 torque and performance but I want a well balanced car with handling feel to match. The M3 is better here. The 550i has a great balance of comfort and handling feel. I believe the M3 does too in brief rides I've had (with the adjustable suspension option).

Based on reviews, the C63 just doesn't like to be pushed on a racetrack. The M3 is the hands down winner here. Even the 550i feels at home at track speeds. Even though I want room and comfort as a daily driver, I want a car that feels at home on a twisty road and a race track.
