I think it depends on the comparison of two specific cams. As a rule, the solid cam will have more aggressive ramps and more area under the curve. With the self imposed 6000 rpm limit, I would guess this is as much for street use and longevity as anything else. If this is the case, the difference in the appropriate solid and roller cams wouldn't be very significant. With equivalent opening and closing events, the lift would be somewhat less with the hydraulic. The lower lift, alone, will stress the rest of the valve train less and add to the life of all the related components.

I might add that if you are not going with solid roller that you might want to look at a solid flat tappet instead of hydraulic roller as you can get near the same performance at a fraction of the cost. Nothing beats a solid roller though
