Well, I'll make the choice a bit easier - the 120cm Profold is out of stock
In a perfect world, bigger is better and the biggest and best is the
150 Profold Octa because it can produce very soft light if required, and if soft light isn't wanted it can either be masked to make it smaller or moved further away, or both - but in a less than ideal world you may not have enough room for it, and your ceiling may not be high enough.
My personal favourite is probably the
140 x 30 folding strip softbox with
honeycomb.
It can be used for glamour/art nude/ fashion because it's the perfect rimlight tool, and also used frontally it places the light exactly where it's needed and nowhere else.
And it's ideal for groups too, where ceiling height is limited. Just place it right up to the ceiling but horizontally instead of vertically - it has plenty of width to light the group and, because it is pointing downwards, it lights the faces extremely well but the light falls off as it travels down the body, putting emphasis on the faces.
But I suppose the most useful general purpose Profold softboxes are the
100 x 100 and the
100 x 70, both of which have honeycombs available for them.
