Two questions:
At high sneak (80+ skill) w/perks can you kill people right in front of other people and they won't notice or find you? If so, I will avoid sneak.
Is a summoned dremora lord (or two with twin souls) capable of wiping high level enemies like Draugr Deathlords (level 40+) while you watch? If they help but can be killed I will lean that way, but if they are unstoppable I won't b/c I don't like the idea of watching the game play itself for me.
Thanks to anyone who has played these styles at high level and can answer.
