Should I go with a 24" or 30" oven/microwave in my kitchen remodel?

We’re remodeling the kitchen and have to make a decision. We either have to do some wall-surgery that involves some re-framing to accommodate a 30” oven/micro floor-to-ceiling cabinet and would push the cabinet closer to the entrance doorway as well, making the entrance to the kitchen even less open, or we can do some cabinet surgery and cut down a 30” cabinet into a 24”. We currently have a 24” oven/microwave and I love how it heats up very quickly.

That said, there is a reasonable chance that we may sell this house in 6+ years and I don’t want to make decisions that are very off-putting for future buyers. Now is the time for us to make this choice, because it would be very impractical to change our minds later. So how important is having a 30” oven to you? I suspect any future buyers would be in their 30’s or early 40’s (unless our schools radically improve).
