It all depends how they sound.... My 1950 0018 Martin w/ Nylon strings does not sound as good as one called a ESPANIA made in Finland also have a Goya Classic {Barf.} Most of the time I play a FG140 Yamaha Picked up at the Flea Mkt for $20 It had the best sound of all of them.Have just put a set of Martin silk and Steel on the Martin hope it will improve. so Who knows. Try different things untill you find what you like THats whats important. Bugger what other people use.
