[Xymon] experience with BMC Patrol

My organization is trying to replace Xymon with BMC Patrol (I suspect its politics more than any dissatisfaction with Xymon). I don't have any experience with this product, but if it is like other BMC products that I'm familiar with calling it a piece of junk would be giving it too much credit. Does anybody here have any experience with this product. What are it's strong points? Weak points?

Thanks, Larry Barber
