HEX much more relaxing (and I go BusinessFirst for free with Star Gold), even with that transfer (a 2-min walk then down two escalators). Added benefit - if I end up on a Liz line train that doesn't go to or from LHR, and odds are that'll happen, it'll be much less crowded for the Paddington-Liverpool St leg.

*£19.25 for half of a return ticket on HEX plus £2.70 tube fee+ = £21.95 vs. £13.30 all the way on Liz line, so £8.65 extra, my time is worth much more than ~£50/hr!
+My last trip I was fare capped from jaunting around London before heading to the airport so I didn't even have to pay this piece. Not sure how that would have worked if I took Liz line to zone 6 after a bunch of zone 1-2 trips earlier that day.
