Wolf or Miele electric wall oven?

I have a chance to purchase floor models of a Miele H4886BP or a Wolf SO30US at good prices. It's hard to find recent reviews that seem to fit, even in general terms, Miele or Wolf ovens.

I mostly bake cookies, but also cakes and brownies. In addition to the normal things a home baker looks for in an oven, I'd like one that doesn't heat up the kitchen too much or have an obnoxiously loud or high-pitched fan.

Does anyone have experience or a recommendation?

Thanks,
Kerrie
