Isn’t the burden of proof on the person making the claim? In this case, you’re claiming they’re worse, so the burden is on you to find a better one. Any would work. But to put the burden on the person claiming, in their own opinion, that they’re simply “the best on the market” doesn’t make sense.
They never asked me. Instead they resorted to name calling, personal attack. So understand why I don't feel inclined to continue this conversation and put more effort into it.
