No difference.  However, I find that 'potent' with 'argument' sounds a bit odd.  Not really wrong, just odd.

As used, potent and powerful are fairly close synonyms in these instances. The meanings would be largely the same with only some nuanced difference in emphasis that few people would likely notice. I find potent to be a stronger adjective than powerful in these uses only because in other contexts powerful can mean other things such as authoritative, or formidable, which make it a more general adjective to use; whereas potent is slightly more specific when referring to the nouns you listed, especially drug, so it's meaning is more targeted and clear in my opinion, but both basically mean the same thing.

I just copied the definitions below from another site, choosing the meaning that I thought fit the noun being described. As you will see there is little difference.

01) potent drug. -- with strong effect; producing a powerful effect
02) powerful drug. -- effective; possessing the strength or qualities to produce an effective result
03) potent force. -- possessing great strength and power
04) powerful force. -- having or exerting great strength
05) potent argument. -- powerfully persuasive, exerting or capable of exerting great powers of persuasion or influence
06) powerful argument. -- persuasive, able to produce a strong effect on people's ideas or emotions

They have a similar meaning, but there is a subtle shade of nuance - rooted in euphony, rhythm, emphasis, tradition, and idiom - so that they are typically used differently, and are not interchangeable. In the examples you gave, "potent" is typically not used - and the phrase "powerful argument" is infrequently heard. In any case, the word "potent" is not often heard. Some examples of usage:

This Amazonian plant is a potent remedy for all kinds of ills. ("Powerful" would not be used here. The phrase "potent remedy" has almost the force of an idiom.)

The enemy gathered a powerful striking force to attack the citadel. ("Potent" would not be used here.)

The doctor administered a powerful drug to stop the tremors. ("Potent" would not be used here.)

He was a powerful man, feared by everyone. ("Potent" cannot be used here.)

He mixed the cocktail, a potent combination of pure grain alcohol, gin, and lemon juice. ("Powerful" would not be used here. The phrase "potent combination" is almost idiomatic.)
