Well, to each his own according his needs, judgment & availability of funds. I never used Cateye TL but I doubt it's any better then the Superflash during the day when the sun is out (next to useless). As far as the short runtime goes, six hours is enough for my weekday rides & the batteries are charged on the weekends. The mount is certainly not elegant but it works fine on my seatpost & if you have a rear rack, then this is a non-issue. Of course, if your riding is on a bike path &/or at night on roads with low traffic, you do not need such a light. I do not use it on the weekends while riding my sport bike out of town on a bike path...
