I went with PW's because they are supposed to be the most reliable. They are pretty expensive, but nothing drives me crazier than equipment that works sporadically.
I have used both CyberSyncs and PW side by side in the field. Both are equal until the temperature gets down to about 5F below zero. Then, the CyberSyncs definitely begin to pull away by maintaining their 100% reliability. I saw no difference at temps above zero (F), so I went with 12 CyberSyncs. Still have 2 PW in my bag but rarely use.
