After spending the day using both, they are both about the same in killing power. The extremely long recon sweeps the P-47s do are completly overkill though, especially against Ostheer which doesn't have much to counter them with.
I don't know why you think that all units that are doctrinal should be discounted. The doctrinal choices Romeo suggested were all from the basic three commanders that every player has. I'm sure you would still count the Tiger as a useful unit for wehr even though it is doctrinal too, and doesn't come standard to new players anymore since the warspoil changes AFAIK.
They are adding something new to warspoils. If you look on the main menu at the loadout you can see a new slot next to victory strike, and if you filter by it you can see there is a gap in the filter categories screen where something new would go.
