Can I check with the experts here on the speed upgrade?

I am on landed fibre and I am thinking of switching over to Unifi 300mbps from Sunway internet.

1. Is it still true that Unifi 300mbps will have higher "priority" for bandwidth over 100mpbs users?
2. Will the latency on 300mbps better than on 100mpbs?
3. Some users reported their speed gets upgraded recently. This is applicable for new subscribers too?

Currently I am using 100mbps the only complain I have is during peak time from 8pm to 11pm internet not very smooth.

This TM block applies to all unifi subscriber? What about those like Sunway digital that leases from TM? I am still able to access the google dns and prawnhub.

Can I check what's SWU 4.0 for 100Mbps plan?

1. Is it free 6 months and 36 months recontract?
2. During this 24 or 36 months contract, possible to get speed upgrade or speed upgrade comes only after you out of contract?
3. Possible to request for just modem (terminal unit) instead of a combo box? I have my own mesh routers and I read bridgemode not working fine?

I am thinking of renewing my Unifi contract but lazy to go to TMPoint, queue is always super long at my area. And currently no speed upgrade too...

Many thanks.

Free 6 months @rm79 too? Thanks.
