I spent 14+ hours doing 200+ transaction, 50+bridge transactions for minting cubes for $L3.
Here is my honest opinion馃憞 We won't discuss tech instead we will focus more on experience they provide.
Best L2s:-
Arbitrum was best amoung all L2s out there RN in terms of gas and speed.
Other than that Base chain was competing with arbitrum in terms of speed while it was costlier than arbitrum one.
zksync was 3rd in my list cosidering those two metric.
