Aerodrome has grown to be enormous, constituting nearly half of Base's TVL. It is by far the most popular app on Base, the largest DEX by many metrics, and often the place where you'll get the best trading experience. Fees are low, and in particular slippage is very low, because of Aerodrome's token model where liquidity is incentivised through bribes and votes. My only criticism is that the full design of this model is hard to understand; it's so complex and took me at least a day to really get it! But it makes so much sense, and as a result it's where you'll find the most liquidity. It's also fantastic for bootstrapping liquidity ahead of time, which makes it very useful for new tokens that have just launched, who want to increase their onchain liquidity. The UI is also very smooth, and the team also provides decentralised mirrors at alternative domains, which is a massive bonus for me. Overall, I'd say it's one of the best DEXs out there, and certainly the best on Base.
