Storms / Airborne / Rangers cost more manpower initially AND reenforce-wise than Grenadiers. They also have higher upkeep.
Grenadiers feed the medic bunker the best. If you lose a 45 reenforce Ranger, all you're going to get back is a 27 reenforce vet 0 rifleman. Vet 3 riflemen can also feed the med bunkers, provided you don't lose whole squads, but by the time you get 6 bodies, the game's probably over. With Grenadiers, you're getting 100% and more for every wounded Gren that gets sent to the bunker. The most you will get from a USA medic bunker is a vet 0 BAR rifleman squad, while the most you can get from a Wehrmacht bunker is a vet 3 Grenadier squad, which is stronger.
Combat stats-wise, vet 3 BAR Riflemen/ Thompson Rangers are stronger than Grenadiers, but they all need weapons upgrades to even compete with vetted Grens, and Riflemen / Ranger vet is not guaranteed on every unit by a long shot, while Grenadier vet is universal. And if you are also able to give your Grens a few LMG34s of their own, shit just got real.
Really, the only infantry blob a Grenadier blob needs to fear is the 3 LT Brit blob. But Brits R Hax, so they don't count. :P
