Not sure if its comparable as I don't have a Dinotte Tail-light, but for a while, I had a Fenix L2D flashlight mounted on my seat post to do that function (with red cover). I believe Fenix is 200 lumen on Turbo?
I have a Fenix L2D myself, and the Fenix's strobe mode is very aggressive, as you already know. Not only is it extremely bright (even brighter than steady Turbo), it also flashes very, very fast, and the beam is focused. I rarely use the Fenix's strobe feature, because the combination of tight beam focus, very fast strobe rate and high intensity
is obnoxious. I save the Fenix's strobe mode for situations where I feel there's imminent danger (people pulling out into my path when I'm at full speed, for example).
The DiNotte strobe mode I prefer (5-pulse) is much less aggressive. The strobe is more of a paced blinking than an actual strobe, alternating 25%-100% output instead of 0%-100%. Since it's a flood beam, it's not as intense either (so aiming it straight back and aiming it downwards might make less difference than you think)
Now the Nova, yes,
that has some actual strobe modes available, in addition to blinking modes. My favorite mode on the Nova is the triple-blink. One-two-three, one-two-three, just like a huge Cateye LD500
Sounds like Dinotte might not be appropriate for a dark trail, but is appropriate if you bike down an unlit highway (for distance), or for commuting through NYC-style traffic and lights, or for daytime. Also appropriate if you are biking solo.
Bingo. To use an audio analogy... if you scream "I HAVE TO USE THE RESTROOM, I'LL BE RIGHT BACK" as loudly as you can, in a quiet library, it's not appropriate. But in the middle of a rock concert jammed with screaming teenagers, or when the only person who can hear you is 1500 meters away...? In that case, no problem
welcome to the rock concert. don't worry about your taillight being too "loud" in this environment
Congratulations on getting the SuperFlash, though, it's a good all-around light. I suggest aiming it dead-level, because its beam's hotspot is very narrow compared to The Taillight We Do Not Name Aloud, or The
Other Taillight We Do Not Name Aloud
As for those who are worried about day time safety - try this. Instead of getting a $100 or $150 Dinotte light - go to your local Target department store and get a child carrier (one that you pull). I bought one on sale for $89.
Brilliant!!!
But can you average 18mph+ with that? 
I think a dinotte taillight works best at night when aimed at the ground behind you. There is no chance of missing that huge red swath on the road surface.
Actually, because the DiNotte's beam pattern is a broad flood, it casts a huge red swath on the road surface behind the bike even when it's aimed
level. Try it for yourself
