Tableau or Power BI (or both)?

I'm about to be unemployed, and I'm looking to get some certificates for either Tableau or Power BI to make myself more marketable to prospective employers. I use Tableau in my current workplace and consider myself a "Beginner". I'm not great at it, but not horrible either (I can more make things look pretty than write extensive calculated fields).

I've never used Power BI, but based on a bit of research, it seems like it's more commonly used in companies that are not already focused on data analytics. I've watched a few videos on Power BI, but never used the app myself. It definitely looks more user-friendly than Tableau, though.

Can anyone offer any insight as to which app would be more marketable to have a certificate in when looking for entry-level jobs? Thanks you!
