Which cam would be better to run a hydraulic or a solid lift?

It depends on the application.

The reason to ues solid lifters is because high tension valve springs put so much pressure on the lifters, that the oil inside the lifter cannot support the strain, oil does not reach the valvetrain, and lash becomes so great and uncontrollable that all h#@! breaks loose. The higher the rpm, the higher the tension needed to control the valves (and spring floating, a much misunderstood phenomenon). Solid lifters are made to handle large-lift, high rpm applications. The drawback, however, is having to make periodic valve adjustments.
If you check with the maker, they will usually tell you how much spring tension their hydraulic lifters will handle. In the end, it all depends on the application. I personally run solid, simply because my springs are VERY stiff.

I would say solid lifters.
