I've been using Claude for almost two years now. Back when everyone was talking about ChatGPT, I installed the Claude Code CLI on my Debian machine.
At that time, Gemini was offering a similar tool, so I decided to compare the two. Honestly, Gemini struggled to generate even a single working function without errors and kept apologising for its mistakes. Claude, on the other hand, was significantly better, even in its early days.
Since then, I haven't switched to another LLM for coding.
Now we're discussing Pi, which supports BYOK. My take is that no third-party alternative can fully replace a native solution, especially when it comes to getting access to new features as soon as they're released. I believe this applies to almost every type of software.
