All academic since it would never actually happen, but it seems like 3rd parties enjoy more success under parliamentary systems, and super unpopular governments can be tossed out more easily. Would things be any better?

It's about how much power the head of state has. If they directly run the government and make policy, presidential (or Prussian Constitutional, in the case of a monarchy). If they don't and the power is defacto devolved to a parliamentary cabinet appointed by the representatives, parliamentary. If you're the French and De Gaulle fucked up your government to maintain power, semi-presidential.
The advantage of parliamentary systems is they fail quickly and cleanly. If the governing representatives lose the ability to vote in a budget, they're not in power anymore (either a new coalition forms organically, or elections are called), while a US system can fuck around for decades with an inability to pass policy. The downside is the difficulty in making and maintaining stable majorities, see Belgium.
