Quick comparison -- the recommendation is just my personal opinion. I myself consider Whizcomms 2.5Gbps plan using GPON ONR to be worse than existing Whizcomms 1Gbps plan with ONT (and worse than Starhub/M1 1Gbps plan, but that is just my personal opionion.
SIMBA 2.5Gbps plan, S$21.80 per month (with GST)
Pros:
1) "True" 2.5Gbps plan with GPON ONT, you can use your own router as the main router. It is possible to use a router with 2.5G WAN and 2.5G LAN to get single connection up to 2.5Gbps download (1.25Gbps upload).
2) You can use your own router with full features
3) You can use more adavnced routers with dual 2.5G ports to have wired 2.5G connection to LAN devices. Optional 2.5G switches can be added.
Cons
1) Using CGNAT as of now, no public IPv4 address. No static IPv4 add-on as of now.
2) No IPv6 support
3) No digital voice add-on as of now
4) Not yet fully deployed to all areas yet,
not proven in terms of stability
Update on 30-March-2024 -- SIMBA just had a major outrage for some users.
5) SIMBA may have higher upfront cost than Whizcomms (eg: S$50 for the ONT).
Why CGNAT is bad without Static IPv4 add-on or IPv6 support?

Whizcomms 2.5Gbps plan, S$21.80 per month (with GST)
Pros:
1) With public IPv4 address
2) The ONR itself is a wired router so you may save one router in the DB Box
3) With Digital Voice add-on
4) Using Singtel network with proven stability
5) Cheaper wireless APs or mesh solutions can be used since there is no need to have 2.5G WAN port.
Cons
1) "Fake" aggregated 2.5Gbps plan with GPON ONR (each ONR LAN port is up to 1Gbps download/upload speed, total speed across all connections: up to 2.5Gbps downalod and 1.25Gbps upload.
2) No IPv6 support (to be confirmed)
3) You have to use your own router in bridged mode (AP mode) to avoid Double NAT. Or you have to live with some limitations of Double NAT if you want to use your own router in router mode.
4) The GPON ONR may have limited features compared to a typical consumer router (let alone better grade routers).

Personal Recommendations: just my personal opinion
Avoid both plans as of now especially for power users.
For an average user who want to have a low Fibre internet plan and do not mind the limitations of the ONR, WC 2.5Gbps may be the way to go. Stability is the most important factor for average users.
The WC ONR limitation may not mean much to an average user. WC 2.5Gbps may be more stable choice between the two as it is riding on Singtel network and it is available now to all users whereas SIMBA is still rolling out the service.
Singtel 2.5Gbps plan
This is quite similar to WC 2.5Gbps plan, only with some differences.
NOT RECOMMENDED.
1) Singtel 2.5Gbps plan support SingTel TV box.
2) SingTel 2.5Gbps plan come with a lousy pair of mesh solution and charge for much higher monthly fee.
3) You probably get a bit better support from SingTel (like changing the ONR or the mesh nodes).
Singtel 2Gbps plan
Same as Singtel 2.5Gbps plan except the total bandwidth is 2Gbps.
NOT RECOMMENDED.
