I voted for Fred, George and Lee.
I reckon they caused mush more trouble.
In OotP, Fred and George caused trouble for Umbridge with thier fire works.
Then they used the portable swamp or whatever it was then ran away from the school.
After they left, Lee put the Niffler in Umbridge's office.

Uhh. I think both groups are really great pranksters. They've made stuff which are a real help to their fellows. The Marauders, and Fred and George and Lee rock.

Its fred and george and lee. Even Marauders didnt pull as much as stunts as the weaselys and jordan did. And the pranks they put on Umbridge is momentum. it was so awesome.

how do u guys know that Marauders are the beginning fathers their invention was the secret to the twins and lee s success and we don't even know all the pranks the marauders came up with but Hagrid agrees with u guys
anyways i voted draw

I chose Fred, George and Lee because I think they are more mischievous than the marauders eventhough the marauders achieved more in an intelectual plain

Merry Christmas everyone!

I voted draw because each group was on a different time. The Marauders were huge pranksters and so were the Weasley Twins and Lee! The Marauders did the map, and the twins did WWW... They had different standards, and also, the Marauders finished school, even if those were difficult times. I guess the twins just had something different on their minds, but in the end, it seems to me like the twins did the same as the Marauders, just like 15 years after them.

I think both groups created a lot of caos and voted for them both, but maybe Fred and George a bit more? I mean they went balistic with Umbridge heh

OMG!! Fred and George's deal during the OWL's was just... WOW... And them and Lee did so many things! So I voted them!

Marauders did their part... in their own time:))

Has to be Fred, George and Lee. They caused a whole bunch more trouble than the Marauders did. Look at Ootp. They pulled so many pranks. Especially with the Weasley Wizard Wheezes. But the swamp and the fireworks. What was it that Lee put in Umbridge's office? A niffler or something? Yeah. They caused more trouble.

Now we all know that the marauders are pranksters at their finest but they are old timers. Fred, George, and Lee Jordan are young. They won't break a hip trying to pull a prank. Yes i know that if it wasn't for the Marauder there would be no map but that wasn'tthe only reason the other would do better. I bet the marauders never tried to blow up a toliet.

I chose both because each have done some pretty incredible and hilarious stunts. The marauders created the map and the twins/lee jordon have wreaked havoc with pranks and gadgets. I think they were both pretty awesome in their own right and in their own time at Hogwarts.

i picked a draw . because the thing is that although the marauders are percepted as to have caused extreme chaos we really dont know there story . so we dont really know much of what they have done. all we know is that there is a map in which they used to sneak around the castle & cause mishief. while on the other hand fred , george & lee jordan , well , we know there story . difference is that maybe back in the days the mauraders were THE mischievious & now its the twins & lee jordan . so it can be a tie . no one will ever know (:

Defineitly Fred, George, and Lee Jordan. They for sure caused the most chaos. But if you think about it, they never really mentioned in the books all the mischievious things the Marauders did.

I Voted Both But I Didnt Mean To

I Meant To Vote For Fred, George And Lee. The Fireworks, The Swamp, Ton-Tongue Toffees, Weasleys Wizard Wheezes, The Niffler And Trying To Send Harry A Hogwarts Toilet Seat In His First Year When He Was In The Hospital Wing

Pure Geniuses

I said it was a draw, because they both caused a lot of trouble in their own time at Hogwarts. It would be funny if they had all gone to Hogwarts at the same time. I bet there would be a lot of rivalry between them on who on was the biggest prank puller. The teachers would love that idea!

I said Fred, George and Lee. Even though if it wasn't for the Marauders finding all the secret passages, the trio definetly caused some serious havoc to school.
Yes, the Marauders caused a lot of trouble, I think it was more bullying than chaos. The Weasley's only bullied Malfoy to stand up for Ron, and Filtch because he's, well he's Filtch.

I had to draw them! They are both soooo awesome groups of people! 8DDDD Sooo funny...... AND INCREDIBLE! At magic!

You just can't beat the pranks that Fred and George pulled. They were greater than any before...hence, the joke shop.

Both "bands" are chaotic...

Definitely both - we don't see that much of the Marauder's schooling life but we do know that they had unregistered animaguses. But for the Twins and Lee Jordan, they cause mischief, definitely in OoTP but who cares - both of the groups enjoyed their school experience at Hogwarts

That is a really tough question

I'm going to say Fred, George, and Lee Jordan... only because with the progression of time they had more weapons so to speak at their disposal. The Mauraders were also hindered for quite a while with the whole becoming anamagi thing that would have taken up quite a bit of time.
