I may be biased but I like the Snark tuner. They are my friends and I did some video demos for them. I like it because the clip stays on the headstock well, it has a super bright display, and it is accurate. I have not had any problems with tuning my uke with it. I use it a lot when I gig playing electric guitar. I gig pretty much every weekend. It is easy to see on a dark stage and I don't get a lot of artifact from ambient noise (music playing through the PA between sets)
