RCZ or C-Class? Help me decide between these two!

I'm torn between buying a Peugeot RCZ and a Mercedes C-Class. The RCZ's sleek design and sporty feel really appeal to me, but I've also fallen in love with the C-Class's luxurious features and strong engine options. I'd love some advice on which car would be best for me - a keen driver looking for a fun ride or someone who wants a comfortable daily drive?
