Define good? An AMD Ryzen 7 6900HS has similar single-core performance, much better multi-core performance for slightly worse power efficiency, compared to an M2. Add in the added advantage of flexibility (you can buy different hardware and switch it up like add RAM and disk and GPUs to your liking) and the fact you can run more things on it (e.g. game), and it's pretty "good". Is it better than an M2? Depends on what you're looking for.
I don't believe it. My M2 Max maxes at around 40W. x86 just isn't that power efficient. You can idle with only one/few economy core turned on running at the lowest power state for longer battery life but x86 is simply very hungry when running high loads and it can't be magically improved. The arch is just obsolete and legacy.
It's got the most confusing, designed-to-lose-stuff UI I've ever seen. And that includes major social media sites, Atlassian's whole... pile of stuff, and (its closest competitor I've come across) a very "advanced" set of Asana projects and workflows.
