Further, the highest tier in the PPS Club is Solitaire PPS (TPP) rather than PPS (QPP). QPP status used to allow entry to SKL F if one is flying C, but in an effort to make the PPS program "more exclusive"

, holders of QPP are only allowed access to SKL C unless flying F - no different to non-PPS pax holding a C bp.
TPP status allows entry to the SKL F, however unlike WP - there is no longer Anytime Access, after the 1st Sept enhancements.
PPS status can only be obtained by flying SQ or MI in C or F. You now have to contribute S$25 000 of revenue to attain QPP, and $250 000 within 5 consecutive years of QPP membership to attain TPP.
And no you no longer get little gifts.

The elimination of the requalification gifts and birthday vouchers are aimed to save the airline more than $5million a year. And don't ask me where I plucked the figure from.
So in some ways, I'd say WP status is even better than TPP from a benefits POV.
FWIW, there is also Krisflyer Gold which is also a *G tier. It is earned after 50 000 status miles on any *A carrier. It does not get you into the SQ lounges in SIN, because they aren't 'designated *G lounges.' Like all other non-SQ PPS *Gs, KF G only entitles access to the SATS lounge in SIN, the 'designated *G lounge.'
If you just want easy status, go for AC*G (Aeroplan Elite) which can be had for 35 000 Qmiles on *A carriers. Easy peasy with a CRWSTAR1 (29 000 x 1.25). The burn rates aren;t the best though. Or you could try matching your WP status over to BD to achieve BD*G, and then you'd only need 38 000 Qmiles on *A carriers to requalify (it is 3000 for blue plus + 19 000 for *S + 38 000 for *G = 57 000 miles to qualify the first time round otherwise). BD is probably *A's answer to AAdvantage in terms of earn/burn, especially with Cash and Miles.
In addition to C lounge access (Clounge?

), you have excess baggage allowance and priority baggage as official alliance-wide *G perks. Which in some ways makes alliance-wide benefits of *G better than OWE.
