We've always been having these debates over whether my choice of tech is better than your choice of tech, same holy wars, different type of tech
The advice today is the same as it was 10/20/30+ years ago, pick what works for you and build something good with it
Nobody will actually care how you built it, regardless of whether its good or crap (although if it's crap you can blame your tools)
There is currently quite strong incentive to establish vendor lock-in for Anthropic and OpenAI. I see the ability to jump between companies quite important, especially for larger users. Right now it should not be hard but it can be much harder in the future.
