I've played steel string guitar for decades. Then, went to uke. I've always used a thump pic because I have a very hard time growing a sufficient thumbnail, even though my fingernails are fragile but fine.
Things changed a lot with a uke. Pics have to be much thinner. I thinned out my guitar pics but not all that much.
The main thing I want to say about thumb pics on ukes is that the pic itself has resonance and makes it's own noise. Drives me nuts. I tried various fixes including putting liquid vinyl on end of pic.
I've discovered that the main source of noise being the plastic itself is to just put a few very small patches of duct tape on the top of the pic close to the edge but not too close. This dampens the sound the actual pic makes. It ends up being much more similar to the sound my fingernails make which is near zero because they are not plastic they are more like cardboard or wood which you may imagine makes much less noise.
I should say that I hear the noise mostly when I'm trying to play a classical piece that demands more tonal consistency and striking all 4 (or 3) strings at exactly the same time (I'm not THAT good!; it's a very simple piece; but that tends to be when I hear it). I think it is a not insignificant effect with lots more than the uke picking if not hard rock.
