I do like both but definitely find him the more interesting and entertaining overall.

I like them both just about equally, but currently I favour Zira a little bit more. I think it's mostly because she's portrayed as a mother during her villanous obsession years - that adds an interesting aspect to the full picture, one that Scar doesn't have. Sure, Scar was an uncle but he never liked Simba at all. I do believe Zira felt at least some affection towards her children, regardless of how brutally she treated them because of her obsession and bitterness.

i pick scar because i cause zira is not more than scar

zira is more power ful
