Why does everyone like the 4.6 so much

[Raw Power]

Why does everyone like the 4.6L, I don't see why so many people could like the 4.6L over the 5.0L. Because when I seen the bore and stroke of the 4.6L I was shocked, I couldn't believe that ford would make a engine with 3.55in bore and 3.54 stroke and put it into a sports car. The 3.55 in bore is way to small to make any real horsepower without a supercharger. The only reason I say this is because I used to have a camaro with a 305ci and the bore is 3.74in and 3.48in stroke and I was told that I would be unable to make more than 300hp because of the small bore and that I would need at least a 4.00in bore to make some real horsepower. The 5.0L is 4.00in bore and 3.00in stroke which is a much better bore and stroke than the 4.6L. I want to get a mustang with a 5.0L, but can someone tell me why so many people like the 4.6L. One more question why do they call the 4.6 a modular motor I have not found out why they are called this. Thanks,
