I have several cases from several company's and for even more games.
Battlefoam, I have 3 very large battle foam bags. To be perfectly honest after trying a few other companies I rather dislike the foam. It's a bit rough imo and can lead to chipping. The custom cut stuff is great if your into static poses but even then things have to be exact or you'll run into problems. I rarely find my self going with Default poses, and rather enjoy converting models. Custom foam just isn't friendly to that. The pluck and pick is nothing special and honesty its on par with the far cheaper sable foam.
The bags them self are pretty high quality, though the size of the bigger bags might be a bit much if your going to be lugging them around all day.
KR- Kr foams is incredible soft. Something i personally feel is a boon as it tends to be a little less rough on paint jobs. In addition i find my self as a collect MUCH endured to the idea that i can have one bag, that i just slip what ever Kr box i want into. DO not be deterred by the cardboard, its surprisingly strong and because of it, it allows you to easily pop unused armies/crews back into the closet for long term storage. Basically you can keep your 1 Kr bag fully loaded with what ever your playing. I currently have one of their larger soft bags and its my favorite at the moment. The harder metal cases are top notch, KR was nice enough to send me a few products to review and give out as prize support for pod-casting. The metal one, was one of them, and i was pretty impressed with it over all.
The do it your self route.
I have a whole slew of home made cases,primarily magnetic that i made for WHFB(RIP). Really easy and really cheap, i think its the route i would suggest going if you have the time. Esp if your crew is largely plastic because they really aren't going to budge. Here is the link for the standard home made case. They are nice sturdy containers, and only cost around 30 bucks. I think i've gotten them on sale for 20 or so at Menards.

They do lock, though i don't think I've ever use that feature. You can just glue down a piece of sheet metal (make sure the magnets stick, lol i made that mistake once doh!) and your pretty much set. one of them the second i think comes full of pluck foam if you don't want to go about magnetizing. With a little bit of work you can pad the top of the case and honestly they do a great job for about half the price. They are all so sturdy so you don't have to worry about something smashing them. The only really negative is i wouldn't leave them sitting in your back seat as that case its a lot more tempting target for a thief then the typical bags.
That you mentioned Armada i think i would go the KR route, it will be much more friendly if your into multi able games. MY one KR back currently transports Flame of War, Armada, Infinity, and Mal. Seriously i can't tell you how great it is to just be able to swap the cardboard boxes in and out as needed.
