Comet vs Monica

Amo and Pimi: Which one to choose between these two

PIMI Pimi
Let's lay out the numbers first: Comet Plus US$5, Pro US$20, Max US$200; Monica Pro US$8.3, Max US$16.6, Ultra US$82.9. Comet is cheaper at the entry level, Monica is cheaper at the high end.
AMO Amo
等等,這是價格曲線交叉耶——US$5進去很甜,可是你之後要升級,Comet Pro US$20一下就比Monica Max US$16.6貴了,這陷阱不能不提醒。
PIMI Pimi
So the real point was never the entry price — it's "whether you'll upgrade." Figure out which tier you'll actually settle at before you commit.
AMO Amo
沒錯,我幫你劃線:只打算用最低檔就選Comet,覺得自己會升級就選Monica,這組是少數需要考慮「未來會不會升級」的情況。
So the conclusion is

The price curves cross: at the entry tier, Comet is cheaper (US$5 vs US$8.3); at the mid-to-high tier, Monica is cheaper (US$16.6 vs US$20). If you'll only ever use the lowest tier, go with Comet; if you expect to upgrade, go with Monica.
