I have an SMAX-40, and it works well for what I need it for.
Light enough to use for extended periods of long runs (1 hour-ish), as its telescopic it is quick to swap between different heights etc.
It has a fair amount of flex at full extension, and if I had huge long runs of work that required this length of pole, I would invest in a SuperLite modular pole, as having played with one, I can't wait to own one.
SO, in summary, I guess it depends on what you need it for, but, for my uses, it's worked very well.
Hope this helps.
