Kaguya gave birth to them before merging with God Tree, so Hagoromo and Hamura were each half as strong as pre-Jubi Kaguya. This is where the "it's difficult to gauge strength" part comes in: Sure the Juubi obtained a greater power than kaguya had alone, but as a rather animalistic creature the Juubi lacked the capacity for more intelligent thought and so for grander strategy etc. So while it may have had greater (Raw) power, Hagoromo and Hamura possessed a greater capacity to use the power that they had. Meaning that their effective power was comparable.

It also ignores effects like redundant powers, or the fact that both the Juubi and kaguya resurrections showed a large degree of synergy. That is, Obito's juubi possessed a power well beyond the summed up strength of the individual Biju, just as Kaguya possessed a power well beyond a Juubi plus a million (give or take) regular ninja worth of chakra. Thus, when the Juubi was split by Six Paths: Chibaku Tensei, the individual parts likely possessed less power than the Juubi alone.

Because of the lack of precision, i think it's irrelevant to discuss whether Juubi Hagoromo was 1,2,3, 5 times as strong as his base. But we do know he wasn't 100x stronger, just as we know that he did in fact gained power. Meaning he was between several, up to perhaps a dozen times stronger as his base, depending on how you want to calculate his power.
