As a new player should I pick these up or the Ixalan set?

The single color mana base appeals to me. So many pre con sets have lots of colors.

Ixalan commanders all look pretty clear to use with the only dog in the set being Ahoy Matey’s.

Now this new Foundation set is out. Is it too simple or under powered? Not enough to grow into?

Or is it about on par with Ixalan?

Delinus Linux?
