If you have any questions about the "best" cooking utensil to buy then you should look at the site for The America's Test Kitchen:
America's Test Kitchen
All they do there is test different appliances, no matter how small or large and tell you the results. They also test for the best cooking flour, best recipes, best cooking chocolate, best cooking pan etc. All the information is there about the runner ups and why they weren't well liked too.
I needed to buy a new can opener and looked it up there. I found the best one and it's been working out really well. The same thing for the best knife. I looked it up, read the test results and got the best knife!
It's a great informational site.
