Tough call for me between Kanile'a and Kamaka.
The Kanile'a was my first Hawaiian made uke (my first love?) and she is a beauty. The abalone fret dots, the UV finish, and I actually like the bridge pin style bridge better - particularly with my mod of koa bridge pins. As for ease of playing, it has a super thin neck (like an electric guitar) and those pretty abalone fret dots are also on the side of the neck, for ease in playing. Sound wise it is incredibly loud and has a very beautiful traditional Hawaiian tone to it. It is light as a feather, it has a slim profile and I love "Waimea" dearly.
The Kamaka is well, a Kamaka. I completely admit I bought it because I had some Kamaka headstock envy when I only had the Kanile'a (which I still feel gets disrespected by the casual uke player - obviously nobody here on UU). Mine is a tenor, with curly koa. I really love the curl in the koa, as well as that gorgeous pearl KK inlay. I'm also a big fan of the smoky white tuners, and while it isn't (to me anyway) as pretty a finish as the UV, this satin style is certainly more traditional. Sound wise it isn't nearly as loud as my Kanile'a, and I'm still searching for the perfect strings for it. I have ordered some Kamaka strings (I know nobody likes them but I want to see it played with the strings the factory feels it should have on it). It feels a lot more solid than the Kanile'a. It is heavier, and chunkier. But I love "Pele" as well. Plus, there is something to be said for the history/tradition that you find only with Kamaka. I got so tired of people telling me, "You should have bought a Kamaka...there is only one Hawaiian manufacturer, and that is Kamaka...etc." I now see why they did. I feel like I'm playing a piece of musical history, and the tradition of the ukulele whenever I play Pele.
So which is my favorite? Tough to say. I've been playing the Kamaka almost exclusively lately (but that could be because she is the new kid on the block). I did spend a while a couple of days ago playing a song on Pele, then immediately playing it on Waimea, and so on. They are really different but I love them both - equally. I guess when I want to have flash and style (and the low g tuning) I go for the Kanile'a. When I want substance and tradition - with the High G tuning (or just want to show off the KK) I use the Kamaka.
Still I can't help but feel that the Kanile'a is my spouse, and the Kamaka is the mistress...(especially when Kristen at Kanile'a is so sweet, then I feel particularly guilty for "cheating on" Waimea the K2 in favor of Pele the HF3).
