It can alternatively build a Tank Commander – a skilled squadron officer for the Astra Militarum, mounted in a Leman Russ. The kit includes cosmetic options such as a searchlight, handles, and a choice of an exposed crewman or closed hatch. It also sports a hull-mounted secondary weapon – a lascannon, heavy bolter, or heavy flamer – and can be equipped with two optional sponson-mounted guns – a pair of heavy bolters, heavy flamers, multi-meltas, or plasma cannons. This tank can be built with one of seven powerful turret weapons – a battle cannon, demolisher battle cannon, eradicator nova cannon, executioner plasma cannon, exterminator autocannon, punisher gatling cannon, or vanquisher battle cannon – allowing you to arm your Leman Russ for busting open tanks, shredding alien swarms, or anything in between. This multipart plastic kit builds a Leman Russ Battle Tank – a versatile armoured vehicle with a wide range of variants. These reliable and formidable tanks can be found in nearly every Astra Militarum regiment in the galaxy, and have become synonymous with the Imperium's fury. Those enemies that do not fall to the bombardment of their cannons and numerous hull-mounted guns are crushed mercilessly beneath their heavy treads.

On top of that, I am aware of Russ Commanders - but I have no idea if Marines have access to tank buffs.

The Predator is a better camper, but that's about the only advantage I can find. The Leman Russ is the primary battle tank of the Imperial Guard, forming the spearhead of countless armoured columns. Leman Russ as a main battle tank It's looking like the Leman Russ is better in every way for only a token points increase.
