I'm a bit sceptical about this after trying the Copilot plugin in VS Code for (mainly front-end) web development earlier this year.
I had to disable it again, because the suggestions from copilot were highly opinionated and - more often than not - wrong.
Now, since that I've started using ChatGPT a lot more, and - especially in the paid version - the 4o with Canvas looks promising, but unfinished, and o1 preview is a whole lot better than "regular" 4o for most things front-end programming.
For anyone using Copilot regularly: Has the it become better over the last 6-8 months? If so I might give it another try...
