Which is more metallic: boron or silicon?

I read somewhere that boron is more metallic. Is it correct? If so, can you please elaborate?


The reason why I'm confused is because 2 factors come into play here:


1. When you move towards right, metallic character decreases.
2. When you move downwards, metallic character increases.


So, which one would win?
Are there any exception cases I should look out for?




Since both are [metaloids](https://en.wikipedia.org/wiki/Metalloid), or semiconductors, look for the [criteria that define them](https://en.wikipedia.org/wiki/Metalloid#Criteria-based). In particular, electronegativity or ionization energy are important.
