I've both vaporized and insufflated 7-OH recently and I can say that oral < insufflated < vaporized as far as potency per milligram. The effects are also wildly different, insufflated and smoked are somewhat similar but smoked has me nodding like I'm railing lines of hydromorphone, whereas insufflated it's more speedy akin to the way oxycodone makes me clean my house without even realizing it. Sorry I don't have much more of an insight on it, my fiance and I cleaned a gram of 63% in something like 3-4 days so our tolerances and tachyphylaxis in general complicated things.
