I think it's arbitrum which is obvious from the infographics you provided on the post. The support from the community is massive and it is obvious that they are providing a solution better than it's competitor or at least they are well preferred by the community in using. I personally has a an arbitrum in my portfolio and I am anticipating that I can get good profits from it as it is well supported by their own community and people are making hype out of it. I hope that they make it up till the bull market and won't have any issues with in their project.
its because zksync haven't released its token yet that I think the TVL is quite low because of that and hardly garner attention, we must remember that although TVL for arbitrum is huge zksync might also be as huge because the active address in zksync said to be few millions even before token released.but if its which L2 that gonna pump i honestly will just place my bet on arbitrum, because as you said the TVL already speaks volume about the state of this coin.
moreover the fact that arbitrum is truly serve its purpose as L2 which being used by many people from the fact that there are plenty of tokens deployed in the blockchain including stablecoins means that its quite popular of a blockchain enough that the big company behind the stablecoin also would think of deploying the token there, I personally quite frequently used L2 like arbitrum for the sake of avoiding ethereum massive fee.
