We've found that the main advantage in using a 96-well microtitre format is that it greatly reduces the chance of mixed up samples at any stage of analysis, from PCR set-up to gel loading. Template DNA or primers can be aliquoted in 96-well format and PCR products can be loaded in a gel cast with a microtitre format comb (2x, 3x or 4x offset). Another obvious advantage is the speed and efficiency of using a 8- or 12-channel pipeter.
Be aware that, if the MJ machine is for U-bottom plates, the manufacturers of U-bottom plates do not recommend their use for PCR (I believe because they are made of PVC). It is preferable to use the V-bottom standard - either 0.2 ml Microamp-type tubes or V-bottom plates. U-bottom MJ machines can be retrofitted with a V-bottom heating block.
