I have some I do by hand and some I do by machine, I usually have at least one of each project going LOL, at the moment I have a scrappy blue star quilt I am hand piecing and a needleturn applique quilt, and want to start a paper piecing quilt by machine as soon as I finish up a few things.
Just do what you enjoy, it's no point forcing yourself to do something that you don't find fun or relaxing, don't worry about what others do
