Compare Two Antagonist Designs for Narrative Effectiveness

You've sketched two antagonists for the same story and you keep flip-flopping. This pits them against each other on theme fit, pressure on the hero's wound, cliche risk and structural flex, so the choice stops being a gut call. Suits novelists and screenwriters stuck at the planning stage who want a reason, not a coin toss.

I have two antagonist concepts for my {GENRE} story and can't decide which to develop. Here they are:

Antagonist A: {ANTAGONIST_A_DESCRIPTION}
Antagonist B: {ANTAGONIST_B_DESCRIPTION}

Compare them across five dimensions: (1) thematic resonance with a story about {CORE_THEME}, (2) capacity to pressure the protagonist's specific wound, (3) risk of becoming a cliche, (4) structural flexibility across a {STORY_LENGTH} narrative, and (5) reader engagement potential. Give a clear recommendation with reasoning, and suggest one modification to the rejected concept that would make it viable if I wanted to use it in a future project.
