Default Anti-platelet agent uses

I'm a little confused about what the difference is between the Anti-platelet agents and their uses (e.g. Aspirin, Abciximab, Clopidogrel, Dipyridamole).

They all seem to be more or less the same, i.e. MI/stroke/TIA prophylaxis, with the exception of Abciximab which is used for more inpatient stuff (e.g. percutaneous transluminal coronary angioplasty). Do we need to know the differences - like which ones are preferred in stroke vs MI? First aid seems to list them as slightly different, and I can't figure out why.

I would be shocked if Step 1 asked you to pick between them for a given indication. Most of the guidelines out there simply say "anti-platelet" medication and don't say which one exactly. You should know the mechanisms of each, and know generally when you would want anti-platelet therapy, but picking between equally good drugs is probably beyond the scope of step exams. They would have to give you some solid contraindications for the others to make the correct answer indisputable.
