Claude vs Gemini: My Use Cases
There's a lot of hype and noise out there regarding Claude and Anthropic, especially after the announcement of Fable 5 and lately Opus 5. I definitely use Claude, I'm not saying I don't! But for many things, I still prefer Gemini 3.6 Flash.
The reason is simple: although my company has fully adopted Claude and strongly encourages its use, being in close contact with Google and other Google developers through the GDE (Google Developer Experts) program means I hear enthusiastic feedback about Gemini as well. So I want to keep testing and using both.
I'm not saying they are completely equivalent for me, but there are specific use cases where I prefer one over the other. Here is how I split them in my daily workflow:
Claude in Claude Desktop #
- Complex multi-tool tasks: Long tasks that involve reading and writing across multiple workplace tools, including company Slack, Hex, or other integrations.
Claude in Claude Code #
- Complex code development: For heavy coding tasks (the ones requiring a good amount of reasoning, like major release refactoring), I rely on Fable 5, Opus 4.8, or Sonnet 5. Often these tasks involve direct integrations via CLI with GitLab (
glab), Google Cloud (gcloud), or our internal MCP servers. - Git troubleshooting (with Haiku): Getting out of tricky
gitsituations (like moving recent commits mistakenly pushed tomainover to a feature branch, or force-pushing the current feature branch tostagingoverriding what was already there — don't judge me: I almost never usegitfrom the command line, I'm lazy!).
Gemini in Antigravity / Antigravity IDE #
- Medium-complexity coding tasks: For medium-to-large feature implementations, I use Gemini 3.6 Flash (high).
- DevTools & Performance Analysis: For tasks involving DevTools for Agents and deep web performance profiling, I use Gemini 3.6 Flash (medium).
- Blog Maintenance & Enhancements: For various work on this blog (e.g., recently translating it entirely into Italian, creating custom skills to write new posts, etc.), I use Gemini 3.6 Flash (medium/high). Spoiler: this very blog post, including its cover image, was generated right here using Antigravity and Gemini 3.6 Flash (Medium)!
Gemini (web / desktop) – Personal Account #
For questions about life, the universe, and everything (the answer to which is always 42):
- Kitten care: How to welcome two kitten puppies when you've never had pets before (a long chat still active after a month!).
- Diet & Nutrition: Advice on diet and meal planning (monthly chats generated using Gems as blueprint, for over a year).
- Home projects: Correctly sizing a photovoltaic solar system (a pinned chat I'll need very soon).
Gemini (web / desktop) – Work Account #
For strictly work-related queries:
- Code analysis: Analyzing minified JS libraries.
- SQL optimization: Comparing complexity and execution cost of SQL queries.
- Error debugging: Analyzing unclear Python or JavaScript stack traces and errors.
- Slack workflows: Advanced Slack automation, app setup, and workflows.
Gemini (web / desktop) – Both Accounts #
Cross-cutting use cases where Gemini is my go-to choice across both personal and work profiles:
- Persistent web searches: Web searches whose results I want saved in an accessible history, rather than lost forever like tears in rain.
- Document & File analysis: Uploading files to extract structured information.
- Tech questions & setup: Resolving technical doubts, configuring tools, making services talk to each other, or understanding AI model internals.
- Brainstorming & Presentations: Generating ideas and structuring content for presentations.
In conclusion: there is no single absolute "winner" for every need. Experimenting with both lets me leverage the best of both ecosystems and choose the right tool for each specific task!
