Is Batman really the Prep. Master ?

We always hear that Batman when given enough prep. time can practically beat anyone ( which is something I personally disagree with ) . We all agree though that Batman is a genius and is one of the most intelligent persons in comics , but is he the best one among all in handling prep. time ?
Aren't there characters that have proven to be very efficient with their prep. time ? Characters such as Reed Richards ? Black Panther ? Iron Man ? Dr. Doom ? Deathstroke & others I fail to remember .

Please , don't put any biased opinions .

In all of comics? No.

Well if this was older, bats would be top 3 behind reed richards and dr doom.

Now haters would put him out of the top five and claim that black panther, tony stark are better preppers

Dr. Doom.

I think John Constantine has much prep. He's gotten himself out of the afterlife, which I doubt Batman can do. And he's a manipulator, which are usually good prep masters, like Doom and Thanos.

He's up there

He's not even top 10 if we're talking all comic characters.

Lol no

He's definitely up there.

Constantine is skyfather level and probably does not need prep. Hes so overpowered that he can make toaa and presence his bitches

Not the top, but not the bottom either.

Not even close.

Hes got to be top 10 I would imagine, haven't seen many better with prep if i'm honest.

He really isn't. The best thing he came up with (on his own) was the Justice Buster. That thing sucked. It could only tank 2-3 hits (one of which was having a 3 story building fall on top of it...) before getting ripped apart by Superman. Even Iron Man's Hulkbuster suits did better against Hulk than that.

Doom is at the top.

Lol wat

Doom is #1

No. Everyone knows that Black Panther is better than everyone in terms of prep...... and everything.
