Definitely Google, with its Gemini Flash 2.0 Experimental. Very high quality, a lot of tools (web browsing, code execution, etc), and surprisingly uncensored if you want.
All have good models, but i agree with jtbx, Gemini it is very good choice.
Sometimes i use gemini-2.0-flash-exp because the gemini-exp-1206 do not work all the times. I think Google is about to release new models
Cerebras alone for the speed of the response - it was quite jarring the first time to see a 70B model respond near instantly.
Cerebras unfortunately won't give you a key right away, apparently you need to join a waiting list because they were overwhelmed by the amount of requests for API access.
