Minato substituted clones for Raijin which closes the gap instantly. Rasengan has a greater destructive power (just check the water towers) but Chidori has a much more concentrated power.

It is correct that chidori is purely an assassination technique. Rasengan has a bit more versatility to it, yet is also a more difficult jutsu. All in all, i'd say they're pretty similar. I comoletely agree with that. Just one thing, the weakness of the Chidori is that the speed required causes tunnel vision, not its short range. So the Rasengan doesn't really share that since its self sustaining.
