What are the advantages or disadvantages or running a ballstyle injectors versus a pinto style injector?

"Accel injectors made by Bosch utilize a pintle to stop the fuel flow out of the injector. Rochester produced injectors utilize a ball valve with a director plate and Lucas uses a disk shape. Each injector design has its own weaknesses and strengths but the pintle design that Accel uses has proven to be the most accurate and repeatable out of the three, albeit the most costly to manufacture."

If you are running boost with varying fuel pressures, it's best to use Lucas disc type.

You will find varying information about what injectors to use. Here is what I'm using. I'm not sure you can beat the price. Before Xmas they were having a sale and I paid roughly $210 for a set of 780CC(75LB) domestic injectors(low impedence).

Your Tec 3 will run low or high impedence injectors as long as they are for domestics.
