You're using it bracketed, near camera axis? Or do you intend to use it also as a standalone strobe on a light stand?
The Streaklight is something I worked with a lot, as I was playing with a portable setup that would have sufficiently short flash duration or jump into HSS. I discovered the Streaklight on my way to buying a second SB-800 and external recycler - at the time, recyclers were $250, and a full Streaklight setup was $300, which was basically getting a free light. As prices came down I bought more units. I used it a lot as a fill flash, with high key sun as ambient. It's awesome. But I also shot a lot of studio and studio quality location stuff with them.
I can't personally speak for the Trio but, comparing on specs alone, the Streaklight wins for me. Output, HSS, price.
I think Profoto is only good if you intend to build a Profoto system and want your on camera flash to play well with you "studio" strobes. Outside of this narrow context, its output vs. price is simply a joke.
