Not too shabby, if I do say so myself.
And of it all, Eisenhorn is far and away the best of the bunch. It's just pure brilliance. More detective novel than scifi/fantasy warfare. The only bad thing I can think to say about it is that the first-act battles are generally more impressive than the grand-finale battles.
But that's kinda the point. The grand arc of the books seems to be that there's no winning or losing. Things simply happen and Eisenhorn defends the Imperium as best he can or will die trying - without end or overall goal. There's always another evil around the corner, so no grand victory can ever finish his work.
But the Horus Heresy overall - while admittedly padded out like a mother****er for effect (and profit) - is shaping up to be pretty damn impressive. Like I say, it's needlessly long, but it's a huge conflict within the WH40k universe and they're detailing events in minute detail because they're fundamental to the nature of not only the books, but the lore of the tabletop game and the subsequent choices and motivations of the people who play it.
Anyways, read Eisenhorn. If you like it, read the first three books of the Horus Heresy series.
