ISPs actually consider many more factors than these. From the simplest possible perspective, the decision is made on destination address. Put strightforwardly, the operational practice and design is the global Internet means that you will get optimal routing (defined for each case) only when you do special negotiations for it, and there is a financial motivation for EVERY ISP in the path to cooperate in such routing. You have somewhat greater control to the ISPs to which you are directly connected, but this still will be dominated by business considerations that are then mapped into technical design. Very different, unfortunately, than Cisco certification labs.
