Yep, I've found Gemini to be the best LLM at most tasks that are not coding. Sometimes Opus wins for engineering, but Gemini holds its own there as well. I also used Gemini to assist me with understanding the details of my (pre-revenue) C-Corp taxes this year. It did a pretty good job walking me through each question I had and raising concern about things I might have overlooked. I validated everything against reliable sources, of course.

Gemini missed on some nuances about the paperwork processes of Delaware. Gemini repeatedly assumed I could do something instantly via an online portal that actually required either snail-mail or the use of an intermediate who actually had API access to Delaware's systems. In the end, these processes took a couple days, and while I got things done in time, I wish I had not taken questions of process at face value, and instead wish I had kicked off the taxes at the end of February rather than week before they were due.
