I've not seen figures but it looks like the Picc carries many more pax to
and from Heathrow than HEx.

HEx is only intended as a replacement for taxis (ie for people who had
it not existed would have taken a taxi), it's not in competition with
any other rail-based modes.

The official Heathrow touts work very hard to push people towards HEx,
so Heathrow Airport Ltd certainly seems to feel that it's in
competition with Heathrow Connect and the Tube.
