I like both. I've done more turning and am moving into more flat work.
I equate turning to sculpture or pottery in the reverse. You take this ' ' amount away and create a shape. There is more 'by feel' and less major planning. Without insulting anyone, it has greater leans towards 'art'. Where turners fall down is we get stuck in the projects (bowls, mugs, vases, urns, pens, wands, walking sticks, et nauseum). Then we focus on finish, paint, texture, piercing, air brush work, etc until you can't tell it was made from wood.
Turning can also provide a quick return on your 1-2 hour investment in the shop. Flat work? see you in 10 hours and then we can see it is starting to 'come together'.
May all your turnings be smooth,
