KF6 vs KF7

Sadly my Delonghi Magnifica is turning the tables after 2.5 years and can’t seem to fix the issue…

Looking at automatic machines now I’m between the KF6 and KF7.

Correct me if I’m wrong but the only difference I could tell between the KF6 and KF7 is the milk frothier. Which I’m not sure if I would actually use, but if enough people tell me it’s really good and they recommend the KF7 then it may swing my decision.

We currently use an electric milk frothier and have really liked it a lot.

I have the whirlpool insider club which has made me gear towards the kitchen aids with the discounts and how much I’ve read good reviews on them. I’m in the US, and budget is under a $1000.
