Based on TVL, swap volumes and number of active Dapps, Arbitrum is clearly outperforming all other L2s. This is quite understandable as Arbitrum does not limit Dapps to build and develop on it but still maintains high safety like on the Ethereum main chain, on the contrary, Optimism requires KYC to be able to build on them. Personally, I think that OP Stack technology is suitable for large businesses and large organizations to use to build their own ecosystems (for example, Base), while Arbitrum's technology is almost for the majority of users.
In terms of technology and future boom, I will choose Arbitrum, but in terms of price, Optimism may be superior because the total supply is less, investment funds are not much as Arbitrum, and importantly The important thing is that Optimism's MM team pushes prices somewhat better than Arbitrum (based on past and ongoing price history).
Yes. It seems Arbitrum is the winner. What I've noticed is that some L2 networks have lower gas fees than others. For instance, I can swap ETH to USDC for less than $0.01 on the Polygon network (using Uniswap), while it the same operation costs more on both the Base and Arbitrum networks. Does this have anything to do with the tech used (rollup vs sidechain)?
I've read that the upcoming Dencun upgrade will make fees even cheaper for rollups, so hopefully Arbitrum will get better over time. Who knows if someday Web 3.0 takes over Web 2.0 as the leading force of the Internet?
