if you had a ball of lead the same size as planet earth, which would be the heaviest, the ball of lead or the earth?

A ball of lead the same size as earth would be heavier.
There's plenty of lead on earth, but most of the planet is composed of lighter materials: iron, nickel, water, etc.

The Earth would be the heaviest because you'll need to get the lead from Earth and nothing on Earth can exist which ways more than the Earth itself,
besides the fact above, the Earth.

I think the question should be which is more massive i.e. has more mass since 'heavy' depends on gravity. Either way, the ball of lead will be heavier and more massive than the Earth.

Planet earth will be heavier because our planet earth core has some elements like bismuth and Francium that adds to its weight that are heavier than lead.So in my own view earth is heavier than lead of the same size

In terms of mass the lead ball is far heavier than planet earth.If you can bring these two balls to another giant planet the lead ball will weigh heavier.

Heavy with respect to where ?
From the mass point of view. The lead ball is bigger. you will be weighted heavier if you stand on the surface of the lead ball compare to the surface of Earth.

obviously ball of lead! simply because it's unformly solid where as the earth is made up of solid, liquid (lighter) and air (lightest) and hollow pockets (like human brain!)
PS: the question at times looks too simple to answer. I really wonder whether there is a catch!

I would say the ball of lead as Earth has air pockets in it. But really you'd have to weigh them in space where there is no gravity so neither would weigh anything.

Definitely the lead. It is much denser. The Earth is mostly Si and oxygen. It has plenty of iron too, but all of those are less dense than the lead.

firstly, you cannot take about wieght in this case as weight depends on acceleration to to gravity (Newtons second law of motion F=MA or in this case Weight = mass x Acceleration due to gravity [W=mg]).
so lets talk about this in terms of mass. pure lead the same size as the earth (assuming its not a hollow sphere) would be denser and therefore have a higher mass as the earth is made up of lead and other elements which have a lower mass.
