>Are premium tools really better than mid-range options?
nope. consumer products are a scam. that you are looking for a 'brand' makes me worry. you don't look for brands.
here is how you choose a tool.
1) you try to know as best as possible what you end up using it for the most. 2) based on that you ask yourself what the best properties of the tool are. and you invent the tool in your head.
3) you try to find a product that is as close to your invention as possible.
4) if you want to do a perfect job, try to borrow a basic tool, see how good of a job it does, based on the experience using the borrowed tool, you can usually better judge what tool to buy.
5) buy it
6) if all options suck, build it.
