My personal choice are Pocket Wizards, but part of that is based on the fact that it is the industry standard, especially in sports venues, so I needed the compatibility. If it wasn't for that I would go for Cyber Syncs as well.
I use the Pocket Wizards Plus II and the Flexx TT5. If you're looking for reliablity within Pocket Wizard go with the Plus II(No TTL though) - Never missed a beat with the Plus II in years. . If you want High Speed Sync and TTL go with the Flexx TT5, however you won't get any consistent triggers beyond 50 ft even with the shield(if you're shooting Canon).
+3 pocket wizards if you are going to stay at this for a while. I've only had one fail and they have a standing $99 dollar repair cost.

Shoot well, Joe
I've also used PWs a fair bit and yes, they are the industry standard. But yikes are they expensive, that's why we call them 'Poverty Wizards'. And as unlikely as it is, I've had (& seen) way more problems with PW than with my Cyber Syncs.
