The siggenes package was developed prior to samr, with the intent that it would replicate the SAM procedure which was at that time only available as an Excel plugin. Given that both siggenes and samr are intended to replicate the results that you would get from the Excel plugin, there may be slight differences between the output from the two packages, but not likely enough to materially affect the results.
That said, you have some data and can use both packages. If you are truly interested, why don't you figure this out for yourself? If I were you, I would want to do my own testing rather than relying on what some random person on the intertubes says.
