Without going in to many details you'll find Profoto and Bronocolor paras are pretty much the same including the price too... so I can't say
I like one or the other better, I own both....
Can't talk about Briese, from what I've seen... they look good!!! There is so much specialized lighting pieces that I like and am looking to buy... but as far as industry standard, all will do the trick...
I just happen to have faith in Broncolor and Profoto!
I loved Broncolor personally for different reasons studio etc. and with Profoto mobility etc.
However, now with Profoto you can have the best of both, Studio & Location... again you can have equivalent with Broncolor too, but it gets heavier with those versos etc. although I like the docks... and the way they're build! I wish profoto would do something similar in their fashion!
One minor thing, probably not as improtant to others is colors... Broncolor looks very attractive to begin with but after a while
just looks aged or like a fashion from the 80' similar to colors of Hy6... this is why I wish SINAR, ROLLEI and LEAF would change it to black a.s.a.p
I personally prefer Black.... if I could, I would even paint my ARRI lights in black too
PS: I am looking in to using Pro ring flash with Profoto Parabolic umbrellas, so we'll see how that goes...
