I liked Season 6, but it was also my first "new" season. My favorite is season 3. Thought Seasons 4 and 5 had the weakest arcs, IMO, but some of the best episodes. If I had to rate each season on "overall" quality, I'd probably do it 3, 2, 4, 1, 5, 6, 7 but even my bottom-ranked ones were still enjoyable, though 7 definitely had the highest annoyance factor between the potentials and the speechs and the FE probably being the biggest let-down as a Big Bad in the history of the series when it had the potential to be the best. (Adam probably ranks as my second-worst BB, but I wasn't expecting much out of him. He was a friggin' Frankensteinian Demon Cyborg. You just don't expect coolness there.)

I've only seen each Angel season once, so I can't really call favorites yet, though Season 3 is probably my least favorite (though I certainly don't hate it.)

My rankings

S4 AtS (Best. Season. Ever.)
S2 AtS (Close.)
S2 BtVS (Leather. Pants.)
S1 AtS (Faith. Torture. Guh.)
S3 BtVS (Faith. Subtext. Guh.)
S3 AtS (Wesley. Guh.)
S1 BtVS (So young!)
S6 BtVS (Realistic depression is rare.)
S4 BtVS (Actually, depending on my mood, swap 6 and 4.)
S7 BtVS (So much potential... sigh.)
Every single ad ever aired during BtVS and AtS, including the ones for feminine products.
S5 BtVS.

Even though S7 makes me more angry.

Even though S7 makes me more angry.

It was the wasted potential, and the unwasted potentials, methinks. Plus, lack of follow-through on season 6, I also guess.

But I can't forgive Angel 3 and 4 for some of the stuff you do, even for meta reasons.

And Buffy 4 is still big in my heart (it was also a big conversion-of-other-people season for me).

But I can't forgive Angel 3 and 4 for some of the stuff you do, even for meta reasons.

Honestly, AtS 4 hit my brain at its exact wavelength or something. I didn't see much that *needed* forgiving. (And I wrote CoCo pre-canon, so, you know, seemingly missing the squick bone.)

And S3, I forgive for reasons that are hella shallow.

S4 AtS (Best. Season. Ever.)

Plei, I share your love. It blew me the hell away. I hope it stands up on the rewatch. I saw "Habeas Corpses" again the other night, and I'd forgotten how kind of annoying all the jealous relationship stuff was.

I think S3 is my favorite Buffy season, followed very closely by S2. I really don't know where S1 goes, but S4 and S5 come before S6 and S7. I don't share the S5 hate, really. On the re-watch, I kind of saw what wasn't great about it, but I still liked it. And as people who hang out in Minearverse know, I'm a "Spiral" fan.

I'm going through S6 now, and I'm about to hit "Smashed" and "Wrecked" and "Gone," which should be delightful (actually, I don't remember minding "Gone" so much, invisibility is fun).

And S7, well...yeah. I was watching it at the same time as Angel S4, and there was no comparison.

I watched most episodes of S4 three times the week they aired.

It was gooooooooooood.

Hmmm...

BtVS 3 (I can't think of an ep that I dislike and the Faith/Buffy arc rocked)
AtS 4 (Every. Minute of it.)
BtVS 2, AtS 2 tie (Gah. All of it - futile, sad, and lovely.)
AtS 3 (there are things in there that make me crazy (Cordelia), but overall goodness)
BtVS 1 (Shiny!)
AtS 1
BtVS 6 (word on the depression arc, but the season fell apart at the end for me)
BtVS 4
BtVS 5
BtVS 7 - (ugh. Add 100 points for Selfless. Deduct a thousand points for potential squandered)

Not putting AtS 5 in there yet, since I need to see the whole season.

If Angel S2 had stopped one episode before Pylea, I'd call it my favourite season of TV ever.

The bastards.

I agree with you, Plei. Season four of Angel was just so frickin' cohesive - start to finish - so consistent emotionally. So great. Even though I like Seasons 2 of BtVS better (because of the 2nd half), I know intellectually that AtS S4 was better. I would rank them:

BtVS S2

AtS S4

BtVS S3

AtS S2

BtVS S4

BtVS S1

AtS S1

AtS S3

BtVS S5

BtVS S6

BtVS S7

AtS S5

Maybe I need to watch AtS season four again. Honestly, I didn't love it. Connor caused me physical pain at times with his badness, and Jasmine was not my favorite big bad at all. I liked the earlier guy better.

Badass Wesley was foamy, though.

Did like the Willow/Fred flirtation in that one episode an awful lot. They're clearly made for each other.
