I have to agree, I don't like either list:
WH list*2 special characters at 1500pts seems a bit much, don't you think.
*Priest should have a ccw to have an extra attack
*Your adepta sorita's (celestine discluded) are just too basic. Your main squads are not faithful and small. I don't think you could've sent any less on your troops. Your Seraphim are a joke, no offence. 5 TL bolt pistols is going to do nothing and have as much assault ability as your sister squad, which isn't saying much. What do you expect from a unit like this
*On Engine is too big a target. Maybe it'll get into CC, probably not though.
*Mainly carnival units and your special characters are going to do the damage. Hopefully your repentia and flagellants don't get shot too much

Your SOB listI'll take a guess that the 279pts includes all that. Your Canoness is just dodgy. She needs a power weapon at the very least. A eviscerator or blessed weapon is preferred. The squad looks like a counter assault squad. Don't you why you have frag and krak grenades for everyone, seems a waste. Your not going to seek out someone in cover or charge into tanks. If your worried about tanks, where our your eviscerators. I'd be worried about enemy shooting as well. Your cheapest model is like 18pts. After that, Vp flow even easier.
3 Celestian Squad (Elites) @ 130 Pts
Bolter (x1); Heavy Bolter (x1); Storm Bolter (x1); Frag Grenades; Krak
Grenades
1 Imagifer @ [36] Pts
Bolter; Frag Grenades; Krak Grenades
1 Veteran Sister Superior @ [36] Pts
Bolt Pistol (x1); Brazier of Holy Fire (x1); Frag Grenades; Krak

Much the same problem as your last squad. This squad has no assault impacting ability at all. The grenades seem wasted
1 Veteran Sister Superior @ [41] Pts
Frag Grenades; Krak Grenades; Meltabombs
Sarissa [5]
Sarissa is useless. Take a power weapon
Exorcist (Heavy Support) @ 175 Pts
Exorcist Missile Launcher
Hunter-Killer Missile
Pintle Mounted Storm Bolter
Blessed Ammunition
Extra Armour
Too many upgrades
To sum up this list*Too many points wasted in grenades
*Practically no assault capabilities. You need power weapons
*Too many useless upgrades
*Squads have mixed weapons, reducing their effectiveness
I'd definetly make some majo changes to both lists
