urgently need feedback on switching from 100mbps unifi to maxis as well (especially in ara damansara area - but general feedback appreciated as well)

they called me with the offer to switch and will provide wifi 6 router and unlimited data for my phone.

my main usage is online gaming as well as torrents.

im worried about line stability and speed stability. also if there is any data cap or something like that. any advise? what do u guys think? to switch or maintain current unifi with the current hardware.

aside from the wifi 6 upgrade, any other advantages? what are the disadvantages?

thanks in advance!
