Are these skills equally hard?

In terms of shoulder strength, which one of these two you find harder?

 

Pike press to Handstand

or

Hands on the edge of a wall, pressing (with straight arms) until your legs are at hand height (I'm using a solid table for this  )

The Pike press to handstand is harder. 

But what we call the 'box press' is a great preparation drill for the Pike press. 

Pike Press is a lot harder for me. Box Presses I can do whenever I want to, even in the middle of the night. Pike Presses are kind of harder and I still need to warm up before doing them!
