it depends on how u want to see it.
there are four fundamental forces in nature, with decreasing order of strength as:-
nuclear force > electromagnetic force > weak force > gravitation force.
both gravity and electromagnetic force are inversely proportional to the square of distance between the centre of mass/charge of the bodies concerned.
electromagnetism is very powerful, but due to lack of free charges, it never dominates the system.
moreover, there are two types of charges,opposite in nature,which atract each other.and get nullified so they maintain the rarity of any free charge.
but there is only one type of mass particle and moreover, due to abundance of mass particles, gravity ,although weakest, dominates the system.it becomes very powerful in long range terms.
infact it is gravity which shapes the universe.

"superior" what do u mean by this...... don't think that why I'm asking questions when I'm supposed to answer...
gravity is the weakest of all forces while the nuclear forces are the strongest. then comes the electromagnetic forces followed by the radio active forces.....
say if u rate nuclear force to be 1 then your nuclear forces are 1/137 times smaller than that followed by u r radio active forces are 10 power -6 times smaller then comes the gravity with a magnitude of 10 power -39 times smaller... these are also called coupling constants
there is another factor which is to be considered that is the distance for which this acts... it's just the reverse thing so now can u decide which is superior
toadd up the first three that is nuclear, em, radio active acts only in atomic level

Most Physics books will tell you that Electro-magnetic force is number three and Gravity is number four.
However our understanding of gravity is limited.
If there are extra dimensions, and gravity is seeping through these dimensions, then gravity would be the superior force. Text books will tell you it's weaker...

Gravity. Because eventually gravity may consume everything . Think about a black hole - light (a.k.a. electromagnetism) cannot escape from it. There is no known limit to the force of gravity but there is for electro-magnetism.

Electro magnetic force is more stronger.Infact the force of gravity is the weakest force in the universe.It is also the most fundamental

electromagnetic force is 10 to the power 38 times stronger than gravity. but gravity is a long range force and itscores over e.m. force in this aspect.
e.m. force can act only in the subatomic level. while gravity is negligible there. the consequences of both the forces are mindblogging at different levels.but in a way gravity is superiour. without it we wouldnt have stars ,galaxies or for that matter even matter

Electro-magnetic force is much stronger than the gravitational force(greater than10^20 times).But since, e-m force is a short-range force, it isn't observed very well. On the other hand, gravity, is a long range force, and affects macroscopic objects more.

Think about the size of a magnet that can lift an entire car... It's roughly the same mass as the car. Now, think about the mass that is trying to hold that car down with its gravity... The entire planet Earth.
Still wonder which is the stronger force?

The gravity. It is long-distance force, while electomagnetic force rapidly decreases with distance within a couple of feet.
Electromagnetic force in fact represents only the force that pulls two objects together, owing to their EM properties, and gravity is the basic force in the universe and applies to ALL objects in the universe.

Gravity is only strong when lots and lots and LOTS of mass is prevalent. The elecromagnetic force is about a million million million million million million times stronger than gravity..or "a 1 with 42 zeroes after it". Gravity is basically a very puny wimp compared to the other three forces in nature.
