INSP has the smaller float (28.9M vs 68.4M), which tends to mean sharper, more volatile moves. Those are the measured differences, not a recommendation, and nothing here is investment advice.

Everything above is measured from the latest completed session and SEC filings.

Which of INSP and TNDM is more active right now?
