with laser and plasma weaponry they don't have the standard issues regarding ammunition, but they need an energy source which requires base materials to create, and parts burn out which need replacing, again requiring not just base materials but also industrial manufacturing, which is something else tyranids don't need to fuel their war requirements.

in terms of ability i'd agree about jonson, but as neithan points out, the issues others have with their perception of him wouldn't make him a great ultimate-leader, but i'd also rule out russ for exactly the same reason - drink, fight, sleep repeat might make him a great leader of men and his own astartes but for most other astartes, as well as a few of his brothers, his public image is that of a barbarian and as such i think he'd actually make a poorer ultimate-leader than jonson. personally i think vulkan is the logical successor to emps as the ultimate-leader of the imperium.
