For Singtel users, if you get the Askey or Arcadyan Wifi 6 mesh solution for free or for low cost, then yes you may want to use it. I believe the wireless performance will be okay if you can use Ethernet backhaul.
The other use case to go with the Airties/Askey/Arcadyan mesh solution is for Singtel TV box, especially if you need to have wireless connection to Singtel TV box. Even then Netgear Orbi is probably a better solution.
Singtel Wifi Mesh add-on plans are pretty bad deal to go with.

1) 2 units of Singtel WiFi 6 Mesh Extenders - Askey, dual band, S$15.14 per month x 24 months = S$363.36
I do not think this is worth it. If you have LAN ports in the rooms so that you can use Ethernet backhaul, you may want to consider Netgear Orbi RBK353 instead, tri-pack at only S$329.

2) 2 units of Netgear Orbi RBK752 WiFi 6 Mesh AX4200, triband, S$33.31 per month x 24 months = S$799.44
Again this is not worth as Netgear Singapore store is selling RBK752 at S$599.
