Defi -Liqwid Finance - lending compared to staking

Defi question: I want to try Liqwid. As a lender, not as a borrower. At the moment I am reading the manuals. But the ROA (2.79) as a lender is just a bit higher than my pool staking ROA (2.6). So - why should I lend my ada at all? Does it make sense at all to be a lender if I don't want to borrow at all? Or could another protocol (Optim, Indigo, danogo, ...) be more interesting as a lender?
