Martin sopranos, hands down. I played a 20's Style 2 that was ridiculously good. My wife was with me in the shop, and when I played it even her jaw dropped - rich, resonant, loud. I have a few Martins that are almost as good as that one was. Sadly, the ukulele was about twice the price of the same model and vintage ones available at other stores, even though it had a replacement bridge. I walked away and continue to regret it.
