I went ahead and made a list of the best possible gear you could get on a warrior for all 3 factions using items solely from OP's list despite the parts I disagree with
Thurgadin:

Skyshrine:

Kael:

So it looks like thurg faction is the worst, least ac, least HP, and the least resists.
Skyshrine faction has the second best ac and HP, around the same resists as kael, but since OP put sleeper's tomb on the list for skyshrine faction for some reason they can get dual SoDs assuming warders are at play
Kael faction has the highest HP and AC, and the best stat-wise weapons
