Both of our vehicles are manuals. I prefer manuals because you can generally buy a used car and not have to worry about what transmission maintenance was done or not done on the vehicle beforehand. After 50k, I start worrying about auto transmissions.
re gas mileage: the reason sticks generally do better is mechanical efficiencies. The torque converter in an auto sucks some of the power, hence the lower mileage. That's changing, however, with newer computers, technology, etc. I've seen a few cars lately that actually get better mileage with an auto. My parents new Corolla got 45mpg on a long road trip with the AC on. It's an auto.
re manliness: You're not a real man until you've had your clutch pressure plate go out and fail to disengage when you're almost to your destination. The return trip involves driving down I395, I495, and I66 in rush hour traffic. Those of you might not know the significance of those roads, but they're some of the most traffic laden in the mid Atlantic. Nothing more fun than speed shifting in bumper to bumper, stop and go traffic, killing the engine when you have to stop, and starting it again with the car in gear. Rev her up to near redline, slam the stick into the next gear and keep on truckin'. :-D
No noticeable damage to the transmission though. I drove it another 20k miles before selling it.
