Since all lithium batteries will have nominal voltages of around 3.7 V, these are just being built with different configurations of serial and parallel cells. So the ROG has four serial cells, the Steam Deck has two, the MSI Claw and the Legion Go have three each. In any case, they'll be using switch regulators to step the voltage up or down depending on the necessity.
Of course, that's never 100% efficient. I'm sure their engineers designed the best product they could for the (cost-limited) components they had available, so I suppose the more expensive ones should be better overall.
