Despite the Fusion and Camry sharing a similar size and layout, they're really aimed at different market segments. It was like the older Accords vs the older Camrys. Some people just drove Accords. And some people just drove Camrys. They often weren't even cross-shopped, for various reasons.
We have a 2011 Fusion Hybrid at work. And it's a fantastic car. It handles better than my Camry, but doesn't ride as nice. I don't like the center stack, or how the HVAC controls are buried at the bottom. It has a severe rearward visibility issue. I like the Fusion seats better. As with any comparison, there are things I like better about one, and there are things I like better than the other.
I think the styling of both are attractive. Each is a very cohesive and well put-together package.
One car isn't "better" than the other in the absolute sense, but each one will absolutely better suit some preferences vs others. Regarding it being an "okay choice", I'd say so; it's been the best-selling sedan for over a decade! That's a consistent track record.
