Advice on this topology problem? (Converging hard and soft edges)

I am trying to create perpendicular edges partway through a square-ish shape. I want one edge to be soft, and the other sharp.

My first attempt:

With this attempt I thought to pull apart the edges on the soft edge, so they diverge away from the hard edge and minimize the issue.

The topology:

The Issue is that I still get a slightly sharpened edge along the top of the object:

My second attempt:

With this attempt I decided to try and terminate the edge loop before it reaches the soft edge, as opposed to pulling it apart to try and minimize the problem.

This fixed the sharp edge along the top, but the top edge now indents in an unsavoury way:

I seem to be able to stop the indent by adding support loops along that edge, but that just recreates the problem I had in the first place.


My third attempt:

With this attempt I decided to create edge loops that flow around the front faces, instead of beginning at the hard edge and terminating or being pulled apart at the soft one.

The topology:

The issue is that the geometry looks drastically different due to the different edge flow and 6 edge pole at the point where the hard and soft edge converge. It isn't a bad result, and I will keep this technique in mind when I want to create geometry like this, but it isn't what I am looking for.


Any help would be much appreciated!
