I think kamui is more advance because of it's intangibility. And the fact that both minato and tobirama are ninjas with high reserves it could be possible that that it really costs high levels of chakra by number of times using it or distance of using it. Kamui also has a long distance teleporting technique which targets other's to be teleported to kamui. though FTG as you said is instant compared to Kamui. In my opinion the most strongest and useful (non kekkei genkai) technique would be shadow clones and with kekkai genkai would be Wood clones. What about the most powerful elememtal technique? for lightning I think it would be Kirin. it takes no chakra and because it's made of natural lightning it can't be absorbed by even the rinnegen and the damage and speed of the technique is unavoidable unless you can tank it. but yes it needs alot of fire techniques to burn but that also could have depended on the weather. since in the anime we saw sasuke using Kirin without any much fire techniques being used. And the last would be is Sharingan considered a technique? since it is literly called a eye technique in english. if yes then, with a sharingan anyone skilled enough can learn any ninjutsu physically possible by him/her.
