The caveat there is that while the Amarr has higher base hp, it's only a 30hp difference, and the Caldari is weighted towards shields (in which we have modules with lower hp totals to begin with). Ergo, it's harder to easily match high shield totals with singular modules because shield modules give less hp on average. The Amarr has fewer slots to try to match anything anyhow (as shorting the Amarr on slots for questionable hp gains and speed penalties is a running theme).

So, while the Caldari can apparently easily match the Commando with a relatively low-level set of mods (with respect to hp), the Amarr has issues match the shields with anything but much more expensive mods. The Amarr can still do so, it just winds up requiring higher skill levels and more ISK.

Rather than suggest the Commando is powerful though, this suggests to me that the speed and slot penalties the Amarr get in exchange for their HP boosts aren't particularly balanced at any level. The Amarr Assault's 30 hp advantage over Gall/Cald assaults is completely washed away by the module slots they get in comparison. This is born out by the fast that a single enhanced shield module or basic armor plates easily compensates for that "advantage" without giving the same speed penalty.
