Does anyone know what the difference is between the two above gels? I'm looking for a gel that will give me some really soft shadows for use in cramped spaces where I can't always fit a softbox of photoflex diffusion. Any suggestions or input would be greatly appreciated.
 
Haven't used the product in question. I personally like the look of tough spun much better than tracing paper type diffusion.

The differences between tough white diffusion gels aren't that big, usually. If the diffusion isn't enough (that is: too much direct light coming through), you can always add a second layer. The light will never be as soft as from a soft box though, because what matters most for softness is the size of the light source.

I haven't used the gels in question, but as AwakenedFilms said, I also think diffusion from cloth-type material is a little nicer. Tough spun is good, but I like Lee "light gridcloth" the most. Double it up with some space in between the layers and you'll get the softest possible light. However, size matters a lot - a gelled lamp will never be as soft as a soft box.
 
You may be able to get your hands on a sample /swatch book of all the gels.

Buy a metre of each and do a little test.

BTW: I always choose diff material by eyeballing the scene with the material in place.

Note also that diffusion /softness is also controlled by the proximity of the source to the subject and the size of the source. The diff screen becomes the source when set in front of a lamp unit . Distant sources are "harder" than close sources. Large sources are softer than small sources.
