The PB Superflash is plenty bright to allow you to be seen. The Dinotte is in a whole other class, it does not merely allow you to be seen, it forces drivers to notice you. With all of the distracted drivers on the road, if I am going to be sharing the road with a distracted driver I want to be the distraction, and the Dinotte tail light does that for me. I have a Dinotte 200L on the front, which I set on flash mode, for the same reason, that light forces drivers to see me. I have a separate headlight (Supernova E3, powered from a generator hub) which I use to see the road - in an urban environment, it is enough to see by.
