MagSafe was awful.
The old magsafe connectors were a great idea, but fundamentally flawed for two reasons. The switch to USB-C was a great improvement.
1. proprietary chargers/cables are hugely more expensive than generic replacements. You can get USB-C chargers anywhere, and use the same charger for everything. I can use my MacBook Air USB-C charger to charge my MacBook Air, my iPad, my android phone, my samsung tablet, my wireless headphones, my Canon EOS R mirrorless camera, my USB battery pack, even the bank of LED lights I use for my zoom meetings. If I travel (vaguely remember about travel from the distant past) I can now pack a single adaptor for everything. NO. I don't want a bespoke Mac charger again.
2. Magsafe had a fatal flaw. All it took was a grain of grit or some other dirt to be caught inside and then the connector would partly connect but not totally, leading for power to sometimes arc across the pins inside, the connector to get VERY hot and eventually oxidizing/corroding the metal. My wife's 2015 Macbook Pro needs regular cleaning to stop the magsafe connector from overheating. I've heard of other people who's connectors have failed completely needing a motherboard replacement.
