Mmmm... But if you find yourself in fog (or other situations where you might not see them first) giving yourself every opportunity to be seen makes sense.
Active (Electrical) reflectors make sense on ribs if you have deep pockets and regularly expect to find yourself in the path of ships monitoring radar, but it's worth bearing in mind that if the feaces fan interface is functioning you might have no power!
In an ideal world you might have your own radar, but without a competent navigator it may not add much value.
I do have one of the much maligned tubes (its poor reputation is one of the reasons Ive not fitted it yet). I'm sceptical that they are totally useless on a powerboat, but of course getting it high enough to be above any waves is an issue too.
