I have the Manduka pro...LOVE IT! Have had it for years and years (and it's used quite regularly) and it's durability, thickness, stickiness, width and length are top notch. I can't vouch for the Lululemon one, though...never tried it. The Manduka is also great for non-yoga core work that requires you to be in various plank positions (front, side)...no slipping even when sweaty.

You should definitely buy Manduka Pro! I bought mine 2 years ago, and it is still my favorite mat ever. It is a bit expensive, but it is worth every penny. It's well cushioned, durable, and made of high quality materials. I found this review on google, it might be helpful for you http://yogamatreviewer.com/manduka-prolite/

I've had my Manduka for about 5 years and still like new. Great cushioning and stays in place.
