Yeah polygon does seem like a nice chain to develop for, I'm assuming the same frontend packages like ethers.js / web3 work seamlessly since it's EVM? The thing I like about working in the Ethereum ecosystem is it is more mature as a whole despite the scalability issues, and there are some very cool projects out there.

If you are looking for other bridges too I recommend checking out Synapse, they let you bridge between a good number of EVM chains and I haven't had any issues with them at all.
