Smart contract escrow for marketing - would this work better on Ethereum L2s?

Been researching this marketing platform on BSC that uses smart contracts for escrow payments between businesses and content creators. Wondering if Ethereum L2s would be better suited.

The concept:

- Businesses lock marketing budget in smart contracts

- OAuth-verified creators join campaigns

- Payment distributed based on real engagement metrics

- Solves fake follower/bot problem in influencer marketing

Currently on BSC (project called Dumblada), but thinking about scalability:

BSC advantages:

- Low fees for micro-transactions

- Fast finality

- Large user base already

Potential on Ethereum L2s:

- Better security guarantees

- Access to Ethereum ecosystem

- Arbitrum/Optimism growing fast

- Base has Coinbase user onboarding

Question for the community: Which chain is best for consumer-facing dapps that need lots of small transactions? Is BSC good enough or do L2s offer real advantages beyond ideology?

Interested in technical perspectives on chain selection for utility projects. What factors matter most for mainstream adoption?
