Be advised, for anything that requires preference or tuning "buy once cry once" is totally fallacious. The most expensive anything is not guaranteed to be the thing that suits you best. Still don't need a slur, but you don't walk into a clothing store and just buy the most expensive things. You have to put in some time and develop some preference before it makes sense to spend hard.

Now if you're just buying an angle grinder, sure, whatever buy the pricey one: it is probably made better.
