Choosing which party to support is a tactical choice, since Bannon rewards the player character with a deathclaw gauntlet schematic and sells the player character apparel at a discount whereas Holmes gives no instant reward, yet has more material with which to make use of the 10% discount.
It is possible, however it is only loosely supported, that Seagrave at one point was supposed to reward the player character with a copy of the railway rifle schematics - possibly to make siding with him more appealing. This is hypothesized due to the note on Seagrave's terminal relating to a "Survival Weapon Idea" that uses railroad spikes as ammunition, and references the possibility of using "steam as a power source."
