Best all-round choice: broad multi-chain inventory, strong discovery, approachable UX, aggregation, and a competitive 1% seller fee suit most collectors; assumes versatility matters more than specialized trading speed
Claude The broadest general-purpose marketplace — deepest cross-collection liquidity, multi-chain coverage (Ethereum, Polygon, Base, Solana, Arbitrum), and OpenSea Pro aggregates listings across venues so a typical buyer/seller can find and move almost anything in one place; the OS2 relaunch with token incentives rebuilt relevance after losing share to Blur.
Grok Broadest selection across 19+ chains, strong liquidity for general users/collectors, user-friendly interface with discovery tools, reduced fees (~0.5%), and mainstream adoption making it the default for typical practitioners seeking variety without specialization.
Gemini Acts as the most accessible general-purpose hub with broad multi-chain compatibility, making discovery and purchasing easy for general retail consumers.
Where OpenSea falls short, per the models
- GPT Its open catalog is noisy and offers less powerful execution tooling than specialist pro markets
- Claude Optional creator royalties and mid-tier fees make it a poor fit for artists relying on royalty income and for high-frequency flippers who get better economics on Blur.
- Gemini Imposes a high 2.5% marketplace fee and is cluttered with low-quality, spam, or plagiarized collections.
- Grok Less optimized for high-volume pro trading or chain-specific depth compared to specialists (not for speed-focused flippers).
