At first look of course the option 2 would be better but there are other factors in terms of what are your other part ie your components and subs.
Flexibility wise of course going full active is always better because you are in more control of your crossover points and slopes. but as you mentioned it low range amps there is alot of definition of low range amp.
But to say that the low range amp is not as good as the mid range amp is something until today that is debateable in terms of sound reproduction quality.
The famous Richard Clark USD 10000 amp challenge since 1980, no one has been able to claim the prize. You can google about richard clark amp challenge.

Basically lets just assume your amps in mind the low and the mid range have almost the same output, measured not rated<. lets say its 100 watt. then in setup 2 the 100 watt per channel is shared between the component and tweeter. therefore you might need to set a higher gain to have a decent sound output.
In setup 1 you have independent 100 watt to each component and tweeter.
Flexibility wise in setup 2 depending on your passive design most dont have db adjuster for the tweeter unless you are playing high end component such as focal utopia or MBquarts Premium and Q series.
What this translate to is if you want to increase the volume of your midbass you will interms increase the volume of the tweeter. sometimes it too ears piercing but you want the bass so how???? <<<

But in setup 1 you can independently control the tweeter gain and the midbass gain separately.

Last factor is of course the built quality.

But end of day its your choice and the type of sound you would like to listen to.
