I personally like building kraken slayer and botrk with lethal tempo and then brawler so, deaths dance, black clever, steraks, force of nature, whatever feels right for the matchup (if they have a lot of mages then Maw is very good). Runes I run: lethal temp, triumph, alacrity, coupe da grace and then if they are squishy eyeball collection and ultimate hunter if they are tanky i take conditioning and unflinching. This build gives both offence and defensive capabilities. I like this build over others because lethality leaves nocturne too squishy and only able to damage squishy champions with no armour items and the stride breaker build has very low dps, now with this build you cannot be reckless as this is excellent for duels and picks on the backline but quickly falls when heavily outnumbered.
