We've been using Triangle JVV in our JV33 for a few years now, it's pretty good, although honestly I didn't really see any noticeable increase in durability or gamut over OEM. It is significantly less expensive though. We just switched to Nazdar/Lyson this week because we were having some difficulty getting the Triangle locally, most of our local vendors didn't have it in stock and it was often a few day+ wait to get it in. We always try to keep it in stock but sometimes you get into a pinch and it's nice to have a dealer within one day that has it in stock all the time. Availability was the only reason for us switching away from Triangle, otherwise we'd keep using it, so just check dealers in your area to make sure it'll always be on hand before pulling the trigger.
