I own both and the main difference is whether or not it will be a walking around gun or not.
The clip magazine always feels like it is in the way when using that one to walk around with as the clip sticks out right in the balance point.
The balance point of the tube feed is clear of any obstruction and so the gun is easier to carry. For me anyway.
I know some folks make a fuss about loading or unloading clips vs tubes but that isn't an issue for me.
If you're just going to punch paper mostly, it don't matter. As for shooting, either will make you smile a lot.
Enjoy the new shooter.
