No difference. Just labelling changes. I believe that the "intensive" version is the newest incarnation.

I like the Perwoll for blacks a lot. Use it all the time.

I've used both, and they're pretty much the same (but utterly superior to any other brand). Great detergent. My fabrics just love it!!

Usually get it from these guys (they seem to be cheapest and shipping is free)

Thank you for your responses. I was hoping they were the same thing, because I ordered one and received the other.

I'm glad to hear you like it... I got it mainly for dark delicates and yoga clothes; should I also use it on dark t-shirts, jeans, etc? I'm currently using the color megaperls for those now.

Thanks!

I use it for all black clothing including all workout clothes, t-shirts, black jeans and pants. Anything/everything black including lingerie.

I have 2 other liquids to use up but when those are gone, plan to give color megaperls a try.

How do you like it?

I find that it's great for natural fibers (cottons, wool blends, etc). It really helps to keep the clothes deep rich dark. Quality synthetics don't really have a fading problem.

For your dedicates (e.g. lingerie) I highly recommend Miele CareCollection Wool Care.
