This or This

This or This (thisorthis.ai) lets visitors vote once a week for the AI they think is best, with no sign-up or login required. The site shows a weekly leaderboard of AI platforms ranked by share of votes, a rank-over-time view across the last 2 weeks and last quarter, and a 'Who's winning where' map showing the top platform by country. Voting weeks run Monday to Sunday in UTC, results update every few minutes, and the site states it scans every AI platform daily. Users can optionally say what they use AI for and which models they use. The page lists 27 AI platforms, including Claude, ChatGPT, Gemini, Grok, DeepSeek, Perplexity, Midjourney, and others, and includes a guides section and sponsored/affiliate placements.
