In fact, if you can dodge plumes 100% , what else is really difficult about titan?
Mass Tumults. Bombs, and bombs+landslide. Neither of which Titan SM does. (And even if you don't think they're necessarily difficult, how often have you seen other people have trouble handling them?)

Titan SM also doesn't throw out nearly as many plumes, which makes them much easier to deal with.

Again, there's really no comparison.
