I don't have a CS kukri machete to compare it to.
I have a preference for the Chiruwa style handle (exposed tang, pinned scales), but in reality, even the hidden tang models are still a full tang, and are massive.
The handles are beefy. I have wide hands and it fits me great. Most smaller kukris feel small in my hands.
Going by dimensions, a 20" Ang Khola is going to be massive compared to the Cold Steel.
Even going with CS's Gurkha kukri (which is their big one), it's 5/16 thick, 17" long and 22 oz. By comparison a 20" AK will be roughly a half inch thick, 20" long and 3 pounds, maybe a bit more. I special ordered one and asked it be no less than 3.5 pounds. After many kukris, even the Dui Chirra I picked up recently, that first 20" CAK is still my favorite.
I can't say enough good about it. It's a chopping powerhouse. It has a LOT more power than any of my 18" kukris -- more than an extra two inches would make me think. However, it's not what you want if you're going after a lot of light vegetation.
As for what to look out for? Not much. Yangdu toldme a wood handle will hold up to extensive use better than horn, but guys here have used the heck out of their horn ones with no problems. Chiruwa or non-Chiruwa seems to be a personal preference thing. Basically, pick what you like the best. Read the section on how to test them. When you get it, run it through the tests. Assuming it survives, chances are it'll outlive your grandkids.

ETA: there is one thing you need to watch out for. It's called HIKV -- Himalayan Imports Kukri Virus. It's an aggressive virus transmitted by contact with HI kukris that makes you compulsively buy more. Sometimes it cross-infects and you get HIkV (small "k") -- Himalayan Imports Knife Virus, or HISV --Himalayan Imports Sword Virus
