Also make sure to stick to your diet especially strictly when swimming, shit always have left me hungry and craving when I was 12 - 13, apparently its because of how cold the water is.
In the end, yes, swimming is easier on the joints and works more muscle than running, its a proper sculpting sport.

What the hell? what a meme
Think about it. In the water you're floating. You don't work hard at all to propel yourself running uses every muscle to a greater effect. When you run are you dragging your torso on the ground? No you hold yorself up under full gravity. Are your arms dangling at your side? No of course not. Swimming drains more energy because you're covered in fluid that drains heat very efficiently so you have to work harder to keep your body temp up. I would do both. I swim a mile 4 to 6 times a week and run 3 times a week.
Swimmers are meant to be aerodynamic. The best body for it is tall and thin. Large muscles hurt you as you increase distance because they require more oxygen and blood to keep moving than smaller muscles. A swimmer should look like Phelps, as that is about as aerodynamic as you can be. It's not as attractive, but it is what wins gold medals.
>You don't work hard at all to propel yourself
Have you ever been in a pool? If you're putting any actual effort in swimming can be hard as fuck. Especially if your form isn't absolutely perfect. If it isn't it forces you to pull against greater resistance. The water being such a strong force of resistance is why most people can walk 50m in the time it'd take a swimmer to swim that length at their fastest. Go swim a 200m Butterfly and tell me that swimming doesn't require hard work at all.
Actually a lot of pro swimmers have shoulder arthritis when they retire (~30yo)
Gotta agree with this. I was one of three swimmers from my graduating class on the Varsity team to escape without some kind of damage to my body. My best friend has no cartilage in his left shoulder anymore, and the surgery he had didn't fix what was wrong. Another messed up his back for a while because he was swimming backstroke and didn't stop at the wall so he slammed head on into it. Two others hurt their shoulders pretty bad by the end of senior year doing something. Several others who I swam with outside of my grade left with injuries, predominately shoulder injuries too. I'd blame much of it on bad form for them. Getting in the habit of doing it wrong can fuck your body up for good after years of wear and tear.
reminder that the average public pool is 25% piss
But piss is 95% water
