Upgrade from Pro 1.0 to EXP 2.0 or just buy EXP 4.0?

Hi everyone.

CSP is currently holding a sale, which I had been waiting for to buy EXP. I plan on using it to make comics. I hear that CSP 4.0 is kind of a let down, but as someone who has only ever used 1.0, are there enough helpful features in 4.0 that make it worth it to just buy that for EXP ($180)? Or should I just upgrade from Pro 1.0 to EXP 2.0 ($113)?
