Does every Picross S and Picross e game have an overwhelmingly amount of 15x15 size puzzles?

The only Picross game on Nintendo Switch I've played so far is Picross S and it stood out to me that half of the puzzles have size 15x15.
Personally, I like more variety in puzzle sizes, so I'm wondering if the other Picross S and Picross e games also have a significant amount of 15x15 Picross puzzles.
