I just cut through a 6x6 pressure treated beam with my Ryobi brushless circular saw. Didn’t even bother to upgrade to a diablo blade. And it worked great!
I made six more similar cuts. No problem.
If I was doing this every day, would I upgrade to Milwaukee? Probably. (More than likely buy a corded saw.) But for weekend home improvement projects, don’t doubt the power!
Same for Harbor Freight. Great tools for light duty use, but if you’re doing big jobs frequently, spring for something better.
I’ve had a HF drill since 2005 and it only recently died. It can probably be fixed since it seems the trigger just wore out, but I got 18 years of use from it for like $15.
There are 2 schools of thought, and both are situationally relevant.
Buy the 2nd last tool you will ever need.
IE, buy light duty. If it breaks and you’ve been using it a lot, you will likely know what features you want, how much to spend etc on the replacement. At which point you buy a more suitable tool.
Buy once, cry once.
If you are spending $200 on a tool, and the $300 is better, maybe just buy the $300 one.
Certainly more applicable to when you already use similar tools, and you need another.
I bought early into the Dewalt system based on people saying Buy Once Cry Once. But the problem is that it locks you into the ecosystem and batteries. Then even if I want a relatively light-duty cordless tool, I’m sort of forced to always go to Dewalt.
If you’re relatively new to DIY work and similar, I do recommend the first philosophy.
