Help me make important life decisions, Internet!

Okay, so Shopko still has all of the seasons of Buffy and Angel on sale for $20. At first, I thought I should avoid it entirely and not purchase any of them, BUT IT IS KILLING ME, INTERNET.

I already own seasons 1-3 of Buffy, and I don't care to own seasons 1-4 of Angel at all.

And while I like certain parts of Buffy season 4, it will be the last season that I buy, I think.

THUS, your choices are:
Buffy, Season 5 (I remember loving this one)
Buffy, Season 6 (Although I loved this one as well. ANGST.)
Buffy, Season 7 (I loved certain episodes, and hey, it's the end of the series)
Angel, Season 5 (We all know that I loved this seaon)

People like sasha_feather and brdgt should avoid reading other people's comments too closely, so as to avoid spoilers!

ETA: OMG ACT II OF DR HORRIBLE WAS SO GOOD! I mean, the first act was all right; I liked the Laundry Song. BUT THEN I WATCHED ACT II AND IT WAS SO MUCH BETTER. I loved Dr. Horrible in the first song. And then I fell in love with Penny when she sang her nice song! AND THEN THERE WAS THE LAST SONG. I love Dr Horrible! I feel so bad for him!

The birds are singing 'cause you're gonna DIE!
