Some have sensors that will really help heat food evenly and will adjust times and power levels depending on what you're doing. Most are just default cook times, but if you haven't tried it out, it's worth it.
I watched a video the other day discussing the sensors in some Microwaves for popping popcorn. Most lower end units don't have these sensors but the ones that do, can actually make pretty good popcorn.
Thanks, I couldn't recall the name of the channel. He does some great content. I never cared about microwaves because I don't use them, but I found myself watching a couple of long videos he did on them none the less.
I watched that same video, and it inspired me to upgrade my microwave game. I've had the same one for like a decade and it sucked. New one has all the bells / whistles and does air frying too. It's night and day compared to the old one
