Especially them Dark Phoenix issues right near the end of the decade.

Never heard of them. Sounds très intriguing.

I think so. It would win and I think it's interesting to find out what else is upnthere.

Well… as the decade actually ends in 1980, you're right.

Also, since "Other" is currently winning so I have to question the alleged supremacy of this obscure 'Dark Phoenix' storyline.

Yes, there it is! I was expecting someone to say it.

And ironically the SAME PERSON that said Dark Phoenix wasn't in the 70s....Beachy, man, what gives?

Yes. Wasn't that clear in the question?
I think it was clear.

I think the description, combined with there being no X-Men choice in a long list of choices, combined with the fact that Phoenix (non-dark) appeared for a very long run of Claremontian comics, indicates an intent to find out what would be your other choice.

Ah, but don't mistake the 70s for a decade; they're 1970–1979, not the actual decade of 1971–1980.

Well now I don't know WHAT to think.

It's true, I have often made the mistake of thinking a decade was a ten-year period.

Well… I'll concede that even 1963–1972 could be called a decade, but I won't agree that 1980 is in the 70's.

Oh, I wouldn't agree with that either. But I do agree that the overall "Phoenix" saga starts much earlier, so most of it was published in the '70s. But it is true that the "Dark Phoenix" turn didn't happen until the last few chapters, which were all published in 1980. Still, it makes sense to think of it as a 1970s storyline.

We talk about "Watchmen" as having been published in 1986, even though it wasn't finished until 1987. 'Tis simply the nature of the serialized funnybook.

In that case, I must side with the majority and say "Other."

Well, what’s it matter? The Dark Phoenix Saga is kind of a hot mess. It had potential when it was actually Jean Grey grappling
with her new powers, but nope—turns out it’s the Phoenix Force all along doing Jean cosplay, like this cosmic entity got bored
at a galactic Comic-Con and decided to LARP as Jean for kicks. And this great entity lets Mastermind, a sleazy illusionist, who
historically can barely trick girl scouts into giving him free cookies, dupe it into a Ms. Peel-inspired Black Queen getup—a cosplay
on top of her previous cosplay—because, of course, Mr. Claremont, a galaxy-eating force must have a secret leather fetish.

The New X-Men bumble their way through like interns on a bad team-building retreat, fighting the Shi’ar Empire’s Gladiator
and his third-rate Legion of Super-Heroes knockoffs, like the Shi’ar photocopied DC’s heroes and forgot to add personality. And
these Shi’ar, already established as blatant intellectual property thieves, have further ripped their entire empire off a rejected Star
Trek B-plot, and they strut in like bureaucrats, demanding Phoenix's head like they wield the cosmic authority supreme.
Why listen to these feathered quacks? They’re just interstellar Karens with stolen Kree tech. Oh, and we also meet Scott’s
deadbeat dad, Corsair, an encounter that curses us with even more Summers family backstory, which eventually serves up a
third Summers brother. Bah—big stakes, sloppy execution, and a “tragic” ending that Marvel just retcons away.

That wasn't true in the 1970s (i.e., 1975 to 1984).

No love for the "Master of Kung Fu" saga, huh? I can see how people wouldn't consider it a "best," but it WAS pretty distinctive. Kind of an ambitious failure.

Wouldn't call it a failure...it lasted over 100 issues,after all. It even became a movie.
It lasted longer than Howard the Duck (and the Howard the Duck movie was much worse than the Master of Kung Fu movie).

It's really good. But this one was about the best

Just yesterday, I managed to get the first three Master of King Fu omnibus volumes for a decent (below original
cover price) price. So I'm finally going to get to reading the early Shang-Chi stories. In the 70s, I was all about
the superheroes but I couldn't afford to buy everything, and the martial arts stuff and Conan and Star Wars books
really never made the cut for me. But, really, that's the beauty of my going back to collect everything Bronze Age
now: to see what I missed.

And I think the Howard the Duck movie can be saved by liberally cutting about 30% of it from the film. There's a
good hour-long TV episode in there, somewhere.
