Digi line is cheap but coverage still not as wide as maxis and celcom
Digi speed also not stable as I can see recently a lot complain not able to get high speed as before and some even getting turtle speed under 4G
Maxis and celcom both are wide in coverage but maxis slightly win in term of speed and 4G coverage .
How ever celcom are cheaper compare to maxis as they offer more data as same price range
