If Bitcoin is also offering its own DeFi then perhaps you can make a fair comparison, but it's not. If you have DApps on Bitcoin then you can compare it with Ethereum, but it doesn't have them. If you can find a stablecoin on the Bitcoin blockchain then you may compare it with USDT on Ethereum, but Bitcoin doesn't have it. So there is really no reason to compare Bitcoin and Ethereum when each one of them is offering a different dish.
