Pertinent if only have a couple of years to go (out of 10? required for lifetime).
Personally, with a travel pattern that could easily include either or both alliances I'd stick with *A because PLT gets many of the same benefits as EXP, whereas *S has very little benefits compared with *G. OW Sapphire is basically a *G-lite.
