I solved this while eating a hard-boiled egg. Not easy, but with some very enjoyable logic! Recommended!

3⅔ difficulty for me, even though I found a way to visualize and pencilmark the constraint very effectively:

@Realshaggy The cell pointed at by an arrow is larger than the other 3 cells orthogonally adjacent to the cell containing the arrow.
E.G R2C1 is greater than R3C2 and R4C1.

Hi Richard, I'm a little bit confused by your formulation of the rules. What happens, if there are multiple largest neighbours? The original rules state that in this case, all arrows are given. Your formulation "THE largest digit" suggests that in this puzzle it can be assumed to be unique?

@Realshaggy: you are right with your assumption, although it shouldn't be an assumption but the exact interpretation of the rules. THE means indeed unique.
I ended up with a puzzle without cells having multiple arrows, so I thought it would be more confusing to write about 'all digits' when there are no cells having such constraints.
First I tried to find a useful place to add an extra cell with two arrows, but couldn't find one that didn't disturb the intended solve. So I chose for the second best option: adjust the rules and the name of the puzzle (without S).
