Worth strings are my personal favourite ukulele strings. I think they handle finger-picking better than Aquila strings (and I do quite a lot of fingerpicking). For strumming, I think they're fairly evenly matched. There's also the matter of which ukulele they are on. Worths seem to sound best on mahogany instruments and Aquilas on koa. I change my mind all the time on this issue, but I very rarely stray away from using Worth or Aquila on any of my ukuleles.
There are two types of Worth strings: clear and brown. Personally, I much prefer the clear strings. It's not just the strings that are clear, but the sound they produce as well.
