It is fun to see the variety of how folks do things.  
My first bow making workshop used a band saw and then nothing but hand tools.  I took another workshop on Osage orange and we sued nothing but hand tools.  
Today, I use power tools infrequently.  E.g., Sometimes I use a hand circular saw might be useful to cut a kerf on an obstinate piece of wood.  On staves with knots in the handle section that will give me fits with a draw knife I use a band saw.  If my cabinet scraper is not making enough progress with smoothing I use an electric sander.  For the most part though, I can work just as fast with or without power tools.  Once you get use dto the them and have your stamina built up for it. 
I agree with the comment that you can mess things up in a hurry with power tools.  However, I can do the same with hand tools too.  Attitude matters.  Jim Hamm said it best in one of his books to go dunk your head in a bucket of water when you get in a hurry.
One day I imagine I will also favor a few power tools to save my body the strain.  I don't jump in and out of a truck bed anymore  

Bottom line use what you are good at and enjoy.  There are plenty of ways to make things work and plenty more to make a mess.  
best of luck.
