Denso IK20TT

I just checked the plugs on my car. They were replaced in august of 2015 at 109k miles. They used Denso ik20tt, the car has 134k mikes now. I know everyone says to use NGK.
Are the Denso ok? I have the opportunity to get a set of NGK IZFR6K for $30. Should I swap them out?

if you get the NGK set, make sure they are legit as there are lot of counterfeit product floating around. I wouldn't loosing sleep much with Denso as they are also par with NGK.
