I can book Economy with Iberia airlines with Chase points for 35,000 points from US to Europe or I can book Turkish Airlines with Citi points for 52,000 points ( I have four time more Citi points than Chase points). Taxes and surcharges are nearly same.

I haven't flown Iberia or Turkish before. I haven't read great reviews about Iberia. I am wondering which airlines to choose? Is it worth saving some points and choosing Iberia?
