Gabriel Angelos is a solid early game pickup and can pretty much face tank anything before tier 3.

They don’t really bring much outside these two abilities and are less good once you have the doctrine unlocked. They can be useful late game too as other elites can be spawned around them, allowing you to support a teammate in an attack with a surprise Imperial Knight spawn. Kill Team Ironmaw is a good early game pickup as they are better than a marine squad and can cheaply be upgraded to kill essentially anything in tier 1. It is also fairly slow making it a much more deliberate weapon. 1v1 the venerable dreadnought should beat any other vehicle but in large scale fights can become a bit lost. The overcharged shot does lots of damage if aimed correctly and the plasma cannon does very good damage to tanks. If you prefer plenty of plasma in your army then the Venerable Dreadnought is good until you unlock his ability as a doctrine. Space Marines have a lot of excellent elite choices to choose from and it really depends on your play style.
