While I love List 2, since it’s so fast and weird, List 1 is a lot better core - at the very least because double Ancients is like the place to start with Sallies
I really don’t care for Prime hordes at this point, but they’re there to be an anvil, so you’d probably not want to swap to two-handed weapons. And at that point I might start looking to Ceremonial Guard for your anvil horde, if the goal is to have a high Nv / US sponge.
Personally, I’d probably bring in some of the speedy elements of List 2 into the groundpounding solidity of List 1. Probably a Scorchwings horde and maybe a couple troops of Lancers?
Here’s a List 1.5 I brewed up between the two:
Army: Salamanders
Points: 2000
Unit Count: 12
Unit Strength: 24
265, Salamander Ceremonial Guard Horde
250, Rhinosaur Cavalry Horde
240, Tyrant Horde
60, Ghekkotah Warrior Troop
60, Ghekkotah Warrior Troop
60, Ghekkotah Warrior Troop
185, Ancient Regiment
185, Ancient Regiment
205, Scorchwing Cavalry Horde
– Fire-Oil
210, Fire Drake
160, Battle Captain on Rhinosaur
– Inspiring Talisman
120, Mage-Priest
– Bane Chant (3)
Lancers didn’t make the cut
I am a big fan of Clan Lord on Raptor, could swap the Priest out for him easily, but the BC is good for grinding and this list is more of a grinder than alpha strike.
EDIT: I dunno about Ceremonial Guard actually, I thought they had ensnare Typically I see Primes w/ brew of strength? I dunno, maybe phalanx and +5 attaks is worth the extra? The Nv brick is nice. Speaking of, I’ve actually been using a Ghekkotah legion for anvil work. Def 3+ is sad but doesn’t matter a lot in a high CS meta, and Nv 25/27 is very tasty! Plus pathfinder is great on a huge unit. Also, I recently was thinking about going Hunters over Warriors for chaff, because of stealthy for a little defensive tech + more light shooting (I love chaff that shoots - like Ember Sprites!)
EDIT2: If you’re interested, Dash28 did both an army review (https://dash28.org/2020/03/28/kings-of-war-3rd-edition-salamanders-army-review/) and an intro on Sallies (https://dash28.org/2020/04/23/kings-of-war-3rd-edition-salamander-introduction/) quite recently. Tho you lists show you aren’t far off in your unit thinking
