I am not that active of a trader but when i trade i mostly use centralized exchanges to be honest and there i mostly use KuCoin. I never had a bad experience with them and everything always worked there so far for me and they are really having a lot of coins listed there so even small projects are tradeable there in a lot of cases. I used uniswap only once or twice because the gas fees are just way to high for me personally. Yesterday i used pancakeswap and it worked great also with low fees, so it's no wonder why a lot of people and projects are switching to the binance smart chain network recently. Yesterday i also used bittrex for 2 trades and i have to say the fees there are pretty high like almost 1% per trade if you don't have those bittrex credits yet.
