Being able to charge on either side is a big deal for me as I move around a lot, plus being able to use 30W USB-C power packs and third party chargers (e.g. Anker) without fear of fire.. a massive boon for me, especially as my phone and Nintendo Switch work on the same cables. USB-C cables fall out with little tension so have had no pre-MagSafe style accidents so far.
The touchpad is better than my 2016, the touchbar is almost pointless to me but no worse in operation, and it runs way cooler and quieter - the past two generations used to burn my legs and were noisy. The only downsides are reduced battery life (not a big issue to me) and the keyboard. I like the reduced travel, but it can "clog".. if they fix that, I prefer its design overall.
