I'vv delidded around 40 CPUs with Hammer & Vice by now without any casualties. Before that I delidded around 10 CPUs with the Razorblade and I made a mistake with one CPU and hat some small cuts in the PCB (thank god the CPU was still alive though).
Regarding these numbers I would say the Hammer & Vice method is really save and easy.
On Average the temps improve from 15-20?C.
