Poll coming up. Maybe indicate your age, and even country of residence, if you don’t mind.
I’m curious; that’s all.

What perfect timing; I even beat the OP to voting.
I voted comic genius. 54, live in the US, but the first time I ever saw the show was because my grandmother in Toronto loved it.
I used to think they were astoundingly hilarious when I was ~12; sometimes I’d laugh until I couldn’t breathe. Now I think they’re clever, but I guess my tastes have changed.

I voted Really Funny but I wavered on Absolute Comic Geniuses.
39; I thought Holy Grail was hysterical when I was a teenager but I think I appreciate more now how difficult their brand of absurdist comedy actually is, while finding less of it to be that funny. If that makes sense.
39, female, USA and voted for comic genius.
Comic genii. 
40-mumble. NZ.
Comic geniuses.
43 USA
Comic geniuses. Living in the USA, I knew them first as recording artists before I was even aware that they had a TV show.
Splunge.
Male, 43, US:
Comic geniuses.
Which, of course, does not mean that everything they ever did was gold.
Nor am I at all sure about labelling any of them individually as a comic genius. But collectively, if they aren’t, then no one is.

I voted that their comedy hasn’t aged well, but I think they suffer from the fact that a certain type of Monty fan thinks it is funny to endlessly repeat parts of their skits verbatim and that this has diminished the brand over the decades. It’s hard to remember how weirdly wonderful the dead parrot skit was when I’ve had it repeated to me a thousand times by nerds.
I think they’re really funny. Their sketch show hasn’t aged that well, and sufferes from pop culture repetition to the point of over-saturation. Plus the “classic” sketches weren’t as funny to me as many of their others.
However, I think the movies still hold up, especially Life of Brian, because there’s a linear story holding it all together that makes sense, with some clever satire in there for good measure.
I’ve always loved silly humour like theirs, from the Goon Show through to Blackadder, but it’s a style that doesn’t seem to have continued much past the 90s. I’d say Austin Powers is the closest, and the last one of those was quite a long while ago. I wish there were more comedies in that vein again (though perhaps there are, and I’ve just overlooked them).
Oh, forgot my particulars: Male, 42, general South Pacific Commonwealth region.
Female, 50+, US of A, and I gave them second funniest on your scale. They only missed out on comic geniuses because a few people have crept past them since their heyday.
Female, over 50. I first saw them in the 70’s in a vacation cottage just over the Canadian border in NY - on an old black and white TV with rabbit ears. I remember the Terry Gilliam bits, the parrot sketch, I’m a Lumberjack, and Spam! I am a big anglophile, and we all giggled at the men dressed as dowdly housewives. I thought they were mostly amusing, but I don’t remember a whole lot other than what I mentioned. To this day, though, I remember the old geezer at the start of the show…“It’s…it’s…it’s…” cue music. Haven’t thought much about them in years, but they were a special part of my long lost youth! They WERE special.
Genius, 44 US
Geniuses.
35, Canadian.
Not everything they did was gold (the episode with the killer blancmange was incredibly tedious, even if the blancmange itself was kind of funny), but more often than not, they were funnier than most, their best stuff is some of the best of the best of comedy in general, and they never got aggressively unfunny.
46 and an Aussie.
Pure genius…
50-USA. Genius though some has not aged well. However, their good stuff is some of the funniest comedy ever.
Guess what my ringtone is.
Male, 57, US
Ditto. Hell, thanks to the LPs beating the show to these shores I was burnt out on them before I even saw them. But my initial reaction to the LPs was “comic geniuses.”
