I love how fast the oven preheats and that you do not have to preheat for air fry. I had a Profile years ago and I’m pleased with this line. 
I like the connectivity- the app is easy to use and it’s nice to monitor bake times without going into the kitchen. 
Convection baking is great for cookies and cupcakes. 
The only downside- the printing on the burner knobs is hard to read unless you are looking at them at an angle. 
My old profile had temperature probe roasting. I miss that.
