Greven,
I didn't see in your question what you would use the kukri for. That makes more difference than the company you get it from. It would be like asking what the best rifle is without stating the task.
Generally speaking, since you asked about specific models, you will not find a modern production kukri that will come close to the CS Gurkha Kukri. No one is close, no one is in the same hemisphere and I don't even think any company is even considering trying. Keep in mind that when I say that I am answering your question about "kukri" and not a big bowie or a kukri machete, which is a machete with a kukri shape, not a real kukri. I have no experience with the extrema ratio kukri but have not seen good reviews. But like I said above, it is not from the same planet as the CS. (Before you think I am a CS employee, I am actually a huge fan of the traditional Nepalese kukri but your question seemed to be leaning toward the non-traditional modern production types.)
If you are considering a traditional model, first I would narrow down what jobs you intend to do with it, how you will carry it and how much you intend to spend. For instance, if you are going to go in the back yard and chop a bit and then shelve it, there is little need to get a top of the line HI or Tora. I would get a cheaper kukri from one of the "Khukuri Houses." If you plan to use it a lot then get the best, either a Tora or an HI. But as soon as you approach either Tora or HI you will be asked the basics; how big are you, what jobs do you intend to do, how are you going to carry it and how much do you want to spend? Answering those questions quickly helps you chose a model. Both Hi and Tora have forums where you can ask questions and talk to other owners.
