One major drawback to the hydraulic lifters-cost. IIRC they were at least 3 times the cost of solids. I've also heard that the design of the hydraulics didn't allow for efficient "burping" of air, and would therefore sometimes get air bubbles. The bottom line is to make an informed decision and do whatever makes you happy.
