I will admit there are a couple heroes that end up being a problem, but only early on. Sivir (Until you learn how to read her boomerang shots), Annie (Watch for the early nuke FB, **** is not cool), and Kat (Shunpo makes rupture really, really difficult to land, and the bouncing dagger is annoying as all sin.) Anyone can be a problem, if they have the skills.
If you really think it will help more to get scream early, get a rank of it. Just be more careful with your mana. You'll be more defensible, but less with the lane control. I for one prefer to play aggressive and loose with Cho'Gath, so I almost always opt for the chained ruptures.
