Would terraforming mars or venus be easier?

I've heard a lot saying that one planet is the obviosly superior choice to the other, but they seem to contradict each other. From what I know:

Terraforming venus has one very big task, but not much else. Assuming you sequest the atmosphere via a mixture of lasering it off, the bosch reaction and sequesting it into carbonates, then you should be able to seed the oceans (formed by the bosch reaction) with cyanobactiria and then venus is terraformed.

On the other hand, mars would involve many smaller tasks; heating the planet with some sort of extreme greenhouse gas, making a magnetic field, making a breathable atmosphere, which you would either need to import gases from other planets or some other way.

Which do you think is easier?

Terraformed Titan

Would it be possible to create a mostly nitrogen and oxygen atmosphere over Titan giving it clear blue skies like on Earth? The views would be awesome though humans could only live inside habitats given the extreme cold. If we could somehow warm it the be more like Antarctica we could at least go out for expeditions on the surface.
