Bottom line
DevTools inspects the page in front of you; Puppeteer drives a browser you control.
The short answer
Both are browser automation, at different levels. The Chrome DevTools MCP inspects and interacts with a live browser session — useful for debugging a page a person is looking at. Puppeteer launches its own browser and scripts it, which is what a repeatable job needs. The distinction matters because one is a debugging aid and the other is a robot.

What would change our mind
A project going archived, or a maintainer changing the install path, flips this comparison faster than any feature release. Both entries are re-checked weekly, and the date above tells you how much to trust the details.

Supabase vs Firebase MCP
Supabase is Postgres with a platform around it; Firebase is a managed document database with tight client SDKs.

Comparison
Qdrant MCP vs Pinecone MCP
Qdrant is infrastructure you run; Pinecone is infrastructure someone runs for you.
Comparison
Filesystem vs Desktop Commander
Filesystem unless you also need a shell — that is the whole decision.
Comparison
PostgreSQL vs SQLite
Postgres for anything shared; SQLite for a file you own and nobody else writes.
Comparison
Supabase vs Neon MCP
