Depends on what model and style you like. WE SCAR looks good and performance isn't bad but its magazine is one of the weakest part of the gun. GHK is durable and uses WA magazine, yet the fps is low (depends on what game you play) but personally I don't like the looks. KA M4 is good in all perspective and is rather balanced in all category. However the magazine can leak but another brand of magazine will help. Personally, I have a SCAR open chamber. I like it because of the looks as well as the performance. I think there are now too many M4 in the field and a I like the SCAR looks.
