Gemini web UI is extremely apologetic and self deprecating at times.
Therefore I was not surprised to experience Gemini spiraling into an infinite loop of self-deprecation - literally it abandoned the first command and spiraled into 5-10line blocks of "i suck"

Right now there is one CLI that influences and stands far and beyond all others. Smooth UX, and more critical some "natural" or inherent ability to use its tools well.
Gemini can also achieve this - but i think it's clear the leader is ahead because they have a highly integrated training process with the base model and agentic tool use.
