I have no clear recommandation for this one... It is really at your choice, as
you feel most convenient.
I tend to use the "as data are stored" approach. If the image has many bands
and
I want all of them in memory, I load them "as is".
If you time series is long, it may be preferrable to use CoverageStack which
allows deferred loading (well, actually the multi-bands image allows deferred
loading as well, but on a tile-basis rather than band-basis).
