Floo powder — Not tiring, can be used by unqualified wizards, but prone to error, and can only lead somewhere with an approved fireplace.
Apparation — Highly flexible and requiring little setup time, but unpleasant, and can only be performed by wizards of age.
Portkeys — Can be used to control the precise destination and time of teleporting, even to places where other modes of transport are forbidden, and can be used by unqualified wizards; therefore, highly regulated by the Ministry.
Side-along Apparation was a later invention by Rowling that negates some of the above logic and screws up some of her plots from earlier books. I would be happy to see Eliezer regard it as impossible in this story.
(I say Apparation instead of Apparition, as the former makes more sense and was the original term Rowling used, before (I presume) an editor made her change it in a later book, which contained many more instances of the word than she’d used before.)
