All have their advantages and disadvantages. IMHO It is tough to beat hotwire airfoils for the combination of ease and accuracy, and if you're willing to use some composites along with the foam cores you can get incredibly slick, precise wings relatively quickly. It isn't as easy as the traditional FT fold over, and is still probably harder than the master series (haven't built one), but the results are there.
I'd be asking what type of aircraft, what type of flying, are you trying to squeeze every bit of efficiency out of the airframe, and how much effort are you willing to put in.
