5G wise should be same for everyone. Hence I think if you stay indoor a lot, then you should instead search for 4G comparison. Before Digi and Celcom merger, I would easily say Celcom good but after their merger, Celcom line sucks a lot (Im using XOX though which ride on Celcom). Personally Im using 2 phones (xox+hotlink on 1 phone plus xox only on the 2nd phone). I have to say things are not looking good for CelcomDigi.
