If you were building a new dApp in consumer web3, how would you choose which chain/L2 to build on to optimize for product growth?

Seems like the two major factors are adoption and gas fees.

imo Polygon is the top choice right now. it's EVM, it's cheap, it's popular, and it's fast. checks all my boxes.

I use ETH as a secure store of value (eg. my important NFTs and crypto portfolio there) but I use Polygon for anything I might interact with commonly (Lens, my trading wallet, my org's keys)

MATIC is also much easier to acquire than most other L2's because you can bridge any asset and then swap to MATIC for free.

More people have eth than matic though - even if it's cheaper and faster, do you think you'd have better growth if you went with Ethereum directly?
