You can try TRX-BUSD on pancake swap. APR is 46%, which is quite high considering that pancake swap is a very reliable platform and that it is a pair with stable coin, so you will not have an awful situation when one token is falling and another one is growing. In this case only TRX will grow. As you see on pancake swap APR is even higher than on Biswap and Beefy, so you should try.
But OP is asking about XRP not TRX:) Ripple not Tron.
Best is still pancakeswap as people point out, but actually you will get a lot more than the APY that you can see from farming XRP-BNB.
Remember, this APY is just your gains in CAKE, but you ALSO still get the fees from the XRP-BNB liquidity pool. So you will gain both that, and CAKE. And then you can still stake CAKE itself;)
