Everything! Boiling a pot of water is twice as fast if not more. More control over temperature. No risk to burn yourself, kitchen towels or other unwanted items. They never need deep-cleaning due to spilled food being burned onto the glass, one wipe with a cloth and it looks like new.

One drawback is they are often bundled with ridiculous touch-controls rather than knobs, even though that shouldn't need to be the case. You can find those without.
