Sure the chips are fast when they run the stuff Apple designed for it, but they don’t seem any faster to me in my work. I will give them efficiency though. I love not having to carry the charge brick everywhere I go.
Both have apple silicon builds now, but it and a lot of other software built for Intel ran at similar performance or better (compared to Intel MacBook / Thinkpad).
I understand why people hate apple, but I've never heard anyone say this (what op said) who has had similar setups. It works a hell of a lot better than my X1 Carbon did.
Docker sucks because it is a linux-ism, not any other reason. And I think most people would disagree with your notion, it really does run circles around basically every other laptop.
Whenever I open IntelliJ on it I can feel the temperature of the room increase. The Intel Macs were terrible for many years.
It'd be worth checking that you're not using an Intel version of WebStorm. I've personally found IntelliJ (largely the same thing as WebStorm) on the M1 to be _extremely_ fast, certainly leaps and bounds ahead of the old Intel Macs. That's the native version, though; via Rosetta it is absolutely painful (the JVM is close to a worst-case for Rosetta).
