Bought both recently and I have to say both are quality products. I like the Clinch Gear because they are very lightweight and not bulky at all. They are excellent for NoGi BJJ. The Sprawl are also excellent quality with good stitching and heavy material. As far as sizing...I'm a 33" waist. I ordered 34" for the Sprawl and the fit wasn't a problem because of the elastic waist and drawstring. If you are an "in-between" size I recommend going bigger if you are getting Sprawl shorts. The Clinch gear shorts are strictly velcro and the 34" shorts for them was too big for me. Trying to "make them smaller" just didn't work. So I returned them for the 32" and the fit was much much better. (side note-- the customer service for ClinchGear was top notch and what you would expect for a reputable company when doing any product return). So for these type of shorts I recommend going down a size if you are an odd numbered waist size. Anyway, that's my quick review. Your milage may vary.
