This is a tough call, but it comes down to which one you are really more comfortable driving. Have you had the chance to drive them both back to back? This would ultimately settle the argument for sure.
The Accord is larger. Would that be a benefit to you? Is this a "me car" or a "family car"?
Looks are subjective, and yet studies show that 60% of what goes into buying a new car are its looks.
Can you afford both and still live comfortable?
Do you want something more comfortable or on the sporty side?
Are you planning to keep the car past three years? Then at that point you might want to consider getting a warranty for either car, which would take away your fears of the new turbo engine, plus cover all the tech that both cars have.
I know which one I would pick, but my wants and needs will undoubtedly be different than yours.
