Modvigil against Modalert
Both contain modafinil. They come from different manufacturers, and differ in excipients and in the regulatory framework under which they were made. The active molecule is the same, so the pharmacokinetics of an equivalent dose are the same.

Approximate window of effect after a single 200mg dose. The molecule sets this, not the label.
No controlled trial has compared these product names against one another. Reports of one feeling “cleaner” have no pharmacological basis at equivalent doses.
