Should i buy Band Of Brothers on Blueray?

[Xx_VEXATOR_xX]

I have watched the whole series for The Pacific, i have heard that Band of Brothers is much better, i wanted to buy the complete series for a very resonable price, but my dad said i should just rent them out, My question/ is band of brothers a series that you go back and watch your favourite episodes? to own... or not to own.
