For your question: I would like to train with the best (and obviously want to have a good chance to get a job afterwards).
Well, not going to comment on that. But let me tell you, there is not only Lufthansa, other carriers and training organizations are good as well, if not even better! And most of all, there are no guaranties in this business, no matter how shiny the name! This applies in particular to flight schools, they'll tell you anything you want to hear in order to get your money! Always be skeptical and get a second or even third opinion if things sound to good to be true! Anyway, lots of good luck to you!
