Colt .22 LR M4 vs. S&W M&P 15/22

Do you have a source for that information? I ask because Walther is owned by or at least partners with S&W and it seems weird to me that they would make the guns for a company that competes with their partner/owner.

EDIT: Just looked it up and they are made by Walther. Weird.

In that case either one will be fine. Colt and S&W are just brand names at this point, so I doubt that one is much better than the other.
