I tried my hand at a manual transmission back when I was first learning to drive, determined I hated it, and have never ever looked back. All the energy spent fussing with RPMs, engaging the clutch and shifting can be better directed towards simply maintaining situational awareness - asking me to worry about transmission while I'm doing all the other tasks involved with operating a coffin on wheels is like asking someone to rub their head and pat their stomach... while downhill skiing. I found the whole experience insanely stressful, I'd stall out, or hit gears wrong, and it was a miracle when I made the damn car operate in an even vaguely appropriate fashion while in a parking lot with no traffic or obstacles - that whole experience colored my impression of driving by making me physically terrified to ever do so.
Whereas with an automatic, I sat down behind the wheel with literally zero prior experience, and after the initial moment of terror courtesy my prior abortive experience with driving a stick, I realized that "Hey, this functions intuitively!" and was on the road within minutes - I still had stress of course, as there were things like positional awareness, maintaining your lane, lane changes, turns, et all to worry about until I'd fully mastered them, but there was never the element of "how the hell do I make this damn contraption move properly?!" to that stress.
The way I see it, driving a manual transmission is a lot like operating your television by getting up and pressing the buttons directly - sure, you can do that and it will work, but why would you when we've invented a machine that does it for you?
