It really depend on area - My frequent area is - Setapak, Mid Valley, Northen PJ, 1U, KLCC, KL Pavilion. Compare to my previous Maxis line, Celcom have much stable line - I mean stable, in term of signal bar and speed.

Setapak - My house is Maxis line deadzone, H+ with no connection, Celcom running fastest among the place I went.

My office at Mid Valley, 22nd floor, Maxis is running less than 2Mbps while Celcom running 3Mbps and above. But call wise, Maxis giving more stable connection (less noise, clearer voice) compare to Celcom.

KLCC - especially inside Parkson, that area is dead zone of both lines, only DiGi survived with 1 to 2 bars. Other place still acceptable, but personally feel that Celcom giving better data speed, compare to Maxis - although the huge Maxis tower is just beside KLCC...

Pavilion KL - deadzone for Maxis, especially inside Parkson Pavillion, reported to Maxis several times with different report no., the last feedback from their L2 technical team is, Pavilion management is rejecting their request to install more signal booster device in the building, so they had no way to improve or resolve my issue.

Other place - Georgetown and JPO - proven Celcom is much stable compare to DiGi and Maxis.

PLUS Highway - KL towards to Seremban is Maxis Territory, U Mobile is champion in certain near town area, Celcom giving slow but stable line for both data and call.

Above is my opinion based on my experience. Cheers!
