There is not necessarily such thing as a best way - it is usually the way that you like the best. I like:

Code:
1. top
2. free
3. free

For cpu - sometimes
Code:
sar -q

is more enlightening. But this requires that you have configured and run sar.

In general top should cover all you needs in realtime, keep in mind you can press 1 to get statistics per cpu core
