Does Zerion support Bitcoin?

No. Zerion covers EVM chains and Solana. GoldRush includes Bitcoin alongside 100+ chains.

Which has better portfolio PnL?

Zerion has a first-class wallet PnL endpoint (realized and unrealized, FIFO). GoldRush focuses on decoded primitives and pricing; you can compute PnL from its data, but it is not a single endpoint.
