I am familiar with the Hall paper but not with the second one.
The reference physics list separate into a hadron physics configuration
(QBBC, QGSP_BIC, QGSP_BERT etc.) and a electromagnetic option (..., EMY
3, EMZ 4). The first handles nuclear interactions, the latter EM
The QBBC uses for some processes the binary and for some bertini cascade
models (you can have a look into the QBBC physics lists in the source
code of Geant4, the reference physics manual or Ivanchenko 2012 "Geant4
hadronic physics for space radiation environment").
All these models have been used in literature for proton therapy
simulations. As far as I know, there is no "best" list and you can use
either of the 3. From some tests a colleague did, in our case QBBC
tended to agree best and therefore we use it, although the differences
were small. (But it depends on what you want to look at, which processes
are interesting for you - some model may be better than the other for
special stuff). If you want to look at particles heavier than protons,
you should consult literature and look for other physics lists.
For the EM part, EMZ may be considered
