For Old Aeon CC, spent at AEON should get about 1.2%. The comparison must take in the factor that you have AEON member card for both cases since New AEON CC requires AEON member card.
New AEON CC

If you just want to enjoy PPL and no nearby AEON store to shop, okay with 0.4% CR, (Old) AEON CC is better since you do not have to subscribe for 3 years RM24 AEON member card.
If you are frequent AEON shopper, new AEON CC is not bad, when you can earn member day extra points.
I can't find the website mention about (Old) AEON CC earn AEON point.
