Also synthetic is thinner, so can get to other regions of engine that normal oil cannot.

Synthetic oil is not actually thinner, it is just more slippery because of the lack of impurities in it. If it was thinner it wouldn't be the same weight. I have used many different kinds of synthetic. Amsoil seems alright, but like someone stated, the batches vary. I seemed to have settled on Valvoline synthetic for now. Castrol used to rock a few years ago, but they are not a true synthetic any more (they use a cracked hydrocarbon base). Mobil 1 is good, but does not have a lot of additives and my cars like to lifter tick with it in there.
