We have an OTR microwave that came with our new home. Great for defrosting and reheating. We have an Oster "convection toaster oven" that comes with a screen rack making it an "air fryer." I don't give a rip about air frying but YMMV. It's the French double door version. The Oster is on a rolling table. This combination is serving us well. Initially we bought the Oster because we planned on getting a Blue Star range. The model I want doesn't have a broiler so the Oster would be used for that. Our current range doesn't have convection.
I don't know if this helps but I'm putting it out there as my experience.
