While certainly I like Hostile Takeover (What self-respecting Weyland player doesn't?), I don't find your arguments compelling. Yes, it provides an on-going effect in addition to an on-score effect (you inaccurately state instead of), but so what? All agendas have an on-going effect of being worth 1 point anyways, so this is true of all agendas.
Additionally, I think you are thinking too narrowly. Yes, Hostile Takeover into Archer synergizes well, but let's not ignore the fact that Hostile Takeover into not-Archer has no synergy. So while Hostile Takeover is great with one Ice, Superior Cyberwalls is good with one type of Ice.
And while you would lose the Superior Cyberwalls' on-going effect, it actually had one to lose unlike Hostile Takeover. I don't see how having something to lose is worse than having nothing to lose. Just because it makes decisions easy, doesn't mean that it makes it better. Besides if you actually want to rez the Archer, you'll be trashing their Fracter, so Superior Cyberwalls' on-going effect is irrelevant.
The main issue is that, yes, it's a 3/1 and not a 2/1, which is why I'm still not entirely sold on it yet.
