I've tried the blue edge and the purple galaxy - use the tall one on the left and the low one on the right.
Currently using the edge on the left and the galaxy on the right. I didn't really like the concave one on the left, but on the right stick it seems to work well.
I'm a bottom tier player, made CS once. I use the Ultra, mainly because they list The Show as one of the games they work well with. They are a bit on the tall side, but they fit my hands perfectly. They do seem to help even me, so if you have any skill with the game they would be worth it.
Amazon has Kontrol Freeks for $17, these are the Ultras https://www.amazon.com/gp/product/B00HSR3CQW/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1
