Let's see
1. I don't use Netflix so no comment
2. I don't have any issues, maybe a buffer from time to time.
3. Seems fine, they say they can throttle when network is under high load but I use a VPN and so far have not faced slowdowns.
4. Reaches expected speeds, with that said my laptop is running on a slow HDD.
5. way better than Unifi, see threads in the Network and Broadband forum, so many complains about ping and routing for Unifi.
6. Yes, however you are on Private IP by default, you will have to ask CS to change your account to Public IP, no costs.
7. Yes, however you will lose the VOIP Phone, due to it connecting to stock router and not modem like Unifi, there are ways to use the stock router as dumb device solely for the VOIP Phone.

Unsure on traffic shaping or throttling, fair use policy is basically just "We throttle person to person (P2P) file sharing during peak periods and the user experience on P2P is on a best-effort basis​."

Regarding 6. Mail server, SMTP port 25 is blocked, you will have to use port 587

I should note that I'm using Maxis Fibre on Maxis Infra, which is kinda rare, most people will be on TM Infra, which is slower.
Eg: I get about 38Mbps max on my 30Mbps plan on Maxis Infra, but someone else using 30Mbps on TM Infra will never see higher than 28Mbps.
This is TM to blame, not Maxis.

Check if your area has Allo City Broadband by any chance? (mainly Ipoh area), they're basically TNB as an ISP
You could say their the landed equivalent of TIME
