which better to track the project tasks and issue a report as following method,

1) save basline on first plan and then tracking the actual on same plan then make comparison reoport up to date you want the report


or

2) creat 2 copy from original plan one (let caled it 1) for tracking the project status up to date as plan by using tracking project automaticly up to date
and make another copy (let caled it 2) for actual tracking by hands, tracking task and put the actual progress and date
then make excell sheet and compare tasks progress for plan(1) and actual (2) task by task and creat shart.

i use the second method while our tasks changes from time to time. for more flexibility. our plan not stable. for one project i have 4 revision of plan.

some task delete totaly and some task are new totally.

so recommend which better method.
