Valve train oiling opinions

I have a 95 360 magnum I'm building. I tore the engine down a found it has the passages drilled for rocker shaft oiling. My question is, which oiling method is better? Push rod oiling or the oil passage in the block/head? I am using trick flow heads and Harlen sharp rocker shafts. The rockers can be ordered with either oil supply method. Any preference/ experience is appreciated. Thanks.
