A modern powerhouse for me would be YSL M7. Try spraying it in the office and wait a few seconds to see the reactions all around. I have not tried this before though. Paul Smith London could be considered a modern powerhouse although it doesn't smell very manly to me. Lasts for days with nuclear sillage.
And lastly Bogart Pour Homme. Longevity of this is insane. Its so strong that it makes my neck burn and red. Another nuclear sillage frag. Wear with caution.
L'eau D'issey pour homme Intense - I tried it a few times but it was quite meh to me.
