Probably because you're using a very performant machine (M1-M4 are extremely capable), but other than responsiveness (which even on an M1 isn't perfect), you got 3 more issues with Electron apps:

1. High RAM usage.

2. The bloat will accelerate as more abstractions are added to web frameworks.

3. Battery usage - the most noticeable issue for me. I've yet to empirically test this, but my guess would be that Electron apps use substantially more power than native apps. I will test this theory eventually.
