At What Point is a Solid Cam Better Than a Hydraulic Cam??

I obviously know the difference between a solid and a hydraulic cam. I was just wondering at what point for a non-race car does it make sense to switch to a solid cam? Or does it for mostly the street and maybe a little strip? I am talking non-rollers here, and small block. I run a Comp XE268 with Comp hydraulic flat tappets, and I am very happy with it.

If it ain't broke....don't fix it.
