Just compare yourself will get the answer.

Also make sure which had better coverage in your area.

Decide based on your budget n how much data you need. Only you will know better than any of us
Your calls n SMS volume will affect your decision too
There is no best plan . Is basically your own decision
If LTE is important consider only Maxis n Celcom as they offer 2 bands n generally better coverage

As advised by both forumers above , get a telco that suits you . Price is 1 thing , coverage is another . Celcom for example sucks at my area for LTE . I lose 15% average an hour on standby if I'm on data since LTE is weak here , it jumps between LTE / HSPDA every now and then . Whats the point of getting a celcom plan with the cheapest package among the 3 when u can hardly use your phone ( for my case )

And also , u never know if telco like DIGI suddenly come out with an attractive plan to attracts ppl to sign up by giving discounts on phone price . It happens before
