I'd say it's not 'either, or' but both.
Practice the theory and technique found in the GT lessons and practice songs too. Have a plan, devote some time to each. They are mutually beneficial.
Good luck, have fun.
"It takes a lot of devotion and work, or maybe I should say play, because if you love it, that's what it amounts to. I haven't found any shortcuts, and I've been looking for a long time."
