I've never cared for either NA over FI or FI over NA. Both have their pros and cons. I care about overall power, performance, handling, looks and longevity than I do fussing over whether a particular engine is FI or not.
At the end of the day, for me at least, it's whether I can appreciate the car or not. Whether it's a 300 HP NA V6 compact luxury vehicle or a 600 HP family wagon. It's all gravy.
Absolutely. I loved the N54 in my dads old E90. I loved the torque it made down low and driving my Camaro reminds me of it because you didn't have to rev the crap out of it to get satisfying acceleration out of it. It was a wonderful driving experience. I have nothing against FI engines( outside really of its hard to make a 4 banger sound good no matter what
But as you said everything has pro's and cons. I would choose the EcoBoost Mustang over the V6 Mustang( if the V6 was still offered). But would choose the V6 Camaro over the 2.0T Camaro.
