Kitchen-Aid here
And no matter what, when it dies (or if I get tired of it) I'll go with Breville just to have everything matching and Breville has proven to me (food processor, coffee maker, milk frother, pizza whatever thing) that they have excellent quality. I don't expect them to last 20 years.
I used to love Kitchen-Aid and it was my brand-to-go for everything but lately they've been disappointing so I'm slowly replacing everything by Breville. Maybe I'll keep just the stand mixer because of the pasta roller. (But having replaced 3 stand mixers in 3 years, all of them with exactly the same problem, sooner or later I'll end up saying farewell too.
