Well, both Germanium $(\text{Ge})$ & Astatine $(\text{At})$ are metalloids but,

$\text{Ge}$ appears earlier than $\text{At}$ in the periodic table.

Also, $\text{At}$ is a radioactive metalloid. It is really rare & has a half-life of 8.1 hours.

Moreover, $\text{Ge}$ is used for its metalloid properties.

I think $\boxed{\text{Ge}}$ should be the preferred answer.

Both At and Ge are metalloids.

Take a look at the periodic table. See that Ge and At are Metalloids? But if you follow trends, you can differentiate the two elements.

Astantine is also a metalloid? It should also be the answer!!
