Dude, just try the things out. It's just undeniable in my day-to-day life that I've been able to rely on Sonnet (first 3.7 and now 4.0) and Gemini 2.5 to absolutely crush code. I've done 3 side projects in the past 6 months that I would have been way too lazy to build without these tools. They work. Never going back.
I tried Copilot a few months ago just to give it a shot and so I could discuss it with at least a shred of experience with the tool, and yea, it's a neat feature. I wouldn't call it a gimmick--it deserves a little more than that, but I didn't exactly cream my pants over it like a lot of people seem to be doing. It's kind of convenient, like a smart autocomplete. Will it fundamentally change how I write software? No way. But it's cool.
