First list seems standard Kreoss pop and drop (Plus Taryn with her fabulous new errata for shooting past colossals), until you get to the Ogrun Assault Corps and Attendant Priest.
Now, I could see the Ogruns working OK, I mean they have decent shooting that can fit into a Pop and Drop list, but it is 11pts that only puts out 5 shots. I just think you'd be better off with Zealot W/
UA and Nicia, or Daughters and Deliverers, or if you really hate stealth throw in Roven for Eye of Menoth and 7 points of anything else.
At the very least, the Attendant Priest isn't needed, unless you're planning on needing some magical attacks, and then...well, you have Errants anyway. Seems you could get better use out of that 2 points.
Second list looks pretty good, though I have to admit I'd be sorely tempted to go for Harby's theme force to save a few points. The Vassals, Wracks and a point from each Crusader and the Avatar becomes Vilmon and two pals and a Mechanik, and , and you get +1 to go first and 3 wall templates to place for harby to hide behind. However, competitively I suppose the vassals and shooting is just too useful in many matchups, so probably what you have is best.
Anyway, just my 2c, though I'm not a tournament player generally so take it as you will
