I find they are almost impossible to stop delivering their payload where you want it. I personally have one with assault cannons, meltas and hurricanes. Due to the stormstrikes, it doesn't need anymore anti-tank on it and I have found when it arrives it will remove or at the very least hamstring several units in one go. Slap some vanguards in it or assault centurions, contract a retainer captain or chaplain with lieutenant supervisor and watch as turn 2 becomes a murder fest of doom wherever you want it.
For your boots, you just run some good ol' intercessors and laugh as the opponent now tries to chew through ether you intercessors in vain to trigger boots on the ground or try in vain to stop the stormravens.
Stormravens I would argue are the only really good thing marines have going for them right now beyond all their other units. It is a flying fortress of firepower and transport goodies. The main thing is that it takes a standard tank statline, puts a few more wounds on it, clamps on the flyer -1 to hit rule and even brings a side of option with hover jets in case you don't care about getting shot at turn 2 (because at that point your payload is down and murdering everything in sight and thus nothing will return fire).
