Did you take a look on voltage and Wh?
mAH can be cheating by having high voltage x Wh, in past it is just 18650 4.2v, now it is layer by layer and 4.3-4.4v, some even 4.5v.
So yes, it can be same mAH but higher Wh by having low voltage, and support of super charge also make them lower Wh so it don't burn in fire.
Also by improving the power lost in charging progress(mean less heat generated/less energy wasted as heat), you can charge more than just old power bank.
Nowadays latest powerbank is charger brick + powerbank, supporting supercharge of Qualcomm + MTK + Samsung + Apple + Huawei + Oppo + Vivo + USB PD 2.0 PPS, it is not just expensive in just Wh anymore, but the supporting of supercharge, not mention some can charge ur laptop with 12v output on USB PD 2.0 PPS to 12V DC convertor as well.
So yes, if you really want the best, go for charger brick + powerbank, the best is with 2 USB output as well, so can supercharge powerbank + 2 smartphone, no need another charger for powerbank and 2 phone lol.

yea it charge bit faster (22.5W vs 18W)
cannot compare the efficiency since my old powerbank is more than 5 yrs age..
but still i prefer the old size despite the advantages of latest tech..
