Manual undoubtedly.
Mac or PC?
PC undoubtedly.
Airbus or Boeing?
I'd rather PC over Mac and android over iOS because I claim to have enough understanding of how the system runs to decide for myself what I want my phone/computer to do for me.
When it comes to cars, it's definitely easier to drive automatic but there's something to Manuel that one can't deny.
Note, when it comes to aircraft design, I'm not sure pilots are generally confident enough to say "I have enough understanding of how the system runs to decide for myself what I want the plane to do".
Although, there definitely are times when even a simple pilot can save a Boeing whereas if he would be flying an Airbus three would be nothing he can do.
