That question is just about impossible to answer I think. Every brand out there has their supporters. I've read many posts from guys using the Walmart off shore made knives cause they beat the crap out of them, or lose them, then just buy another. For their particular needs, they'd never use, say, a Sebenza or Hinderer. And many feel that spending over $25 for a knife is just crazy.
You may be better served identifying what you'd like your knife for, and your budget range. Check the online vendors to see which models appeal to you. Then search the forums and odds are, you'll find reviews already given. If not, everyone here is pretty helpful and not shy about giving their opinion. Lol.
If you can in your area, attend a gun or knife show and try to handle as many different kinds of knives that you can to see how they feel. I've bought quite a few knives that looked great in the picture, but then felt terrible in my hand. It may not be the exact knife you're looking for, but similar enough to see if the ergo's will work for you.
