some questions on power tools

hey,
I'm doing a research project for my university. I'm trying to learn more about power tool usage when it comes to automotive tuning, moding, fixing, etc.

Some people use power tools when moding their vehicle, other's do not. I would greatly appreciate any feedback. Please answer any or all questions that apply to you. This would be a huge help. Thanks!

pneumatic tools generally last longer than power tools.
Electric Impact tools are not as good as pneumatic.
Power tools change performance as battery charge goes down.

Not enough torque for all applications.
Have to recharge batteries (Air compressor is prefered)

Hand Tools and Air Tools

Never need eletricity for hand tools.
Power tools can't get into small areas as easily.
