Three $20-ish subscriptions, three very different bets. A weighted decision engine, 22-row spec table, and 8 persona picks to find which one fits you.
At a glance: all three sit within a dollar of $20/month, but they optimize for different jobs. There is no universal winner — the right pick depends on which job is yours. Read the methodology note
Set the importance of each factor from 0 to 100. Every metric is normalized, weighted, and summed — the ranking updates instantly as you drag.

Each card's bars are that tool's own strengths, on its own terms.
The default choice: strong at almost everything, plus the widest set of built-in tools.
The precision tool: cleanest prose, most reliable code, least prone to making things up.
The ecosystem play: a context window big enough to swallow whole codebases, wired straight into Docs, Gmail, and Sheets.
Past the spec sheet: where each one genuinely wins, where it genuinely loses, who should skip it entirely.
Skipping the multi-way math — here is the direct call for each pair.
Breadth vs. precision — ChatGPT covers more kinds of tasks; Claude does writing & coding noticeably better.
Quality vs. scale — Claude produces cleaner output on 200K tokens; Google trades polish for a 1M-token window.
General-purpose assistant vs. Google-native research tool — closer than the spec sheet suggests outside Workspace.

This is the stuff Reddit threads are actually complaining about — not the headline specs.
Hit the cap and you're switched to a lighter model until the window resets — most people never notice until output quality suddenly drops mid-session.
It's a rolling window, not a hard daily reset — so a burst of ~100-150 messages can lock you out for hours at an inconvenient time.
Google doesn't publish a specific message cap the way OpenAI and Anthropic do, and the wording has changed more than once without a price change.
ChatGPT, Claude, and Gemini all use consumer-plan conversations for model improvement unless you opt out.
Today's ~$20/month is not a permanent number for any of them — all three vendors have adjusted consumer pricing or quotas since launch.
ChatGPT Pro runs $200/month, and Claude Max / Google AI Ultra exist for the same reason: the $20 tier is intentionally rate-limited to push power users upward.
