Seems to be roughly even, with somewhat more TSA PreCheck-only members than Global Entry members (including NEXUS and SENTRI).

As of March 2023, TSA said [1]: "TSA PreCheck® application program has surpassed 15 million active members" and "Thirty-two million travelers now benefit from TSA PreCheck expedited screening after being vetted though TSA PreCheck ®, U.S. Customs and Border Protection’s Global Entry or another federal vetting program."

As of September 2023, CBP announced stated that there were over 12 million Global Entry members in a press release. [2]

This appears to include SENTRI and NEXUS members, since as of July 2022 it was stated: [3] "There are over 7.6 million participants enrolled directly in Global Entry, and over 1.8 million members of NEXUS and SENTRI that also receive Global Entry benefits."
