Certainly you can give more attention to detail as a hobbyist than most factories can afford. Then it becomes a question of skills and how deep you want to get into the process. An 80% frame will give you the most to work with but it's gonna be fairly intensive in tools and time. Pretty much any good 1911 build will be.
Also before you get to deep into it, make sure you can score all the parts you want. Not everyone is exportable from the states so you might have to settle for your second or 3'rd choice of internals, barrels, ect.
