Which way to go from Boise to Challis Idaho?

Which is the easier way to go to Challis Idaho from Boise, highway 55 through horseshoe bend/garden valley or highway 21 through idaho city? My concern is the steepness of the mountain from boise to horseshoe bend! Is highway 21 more of a gradual climb?

    Thanks, I wished I read this before I left! I came up 55 only because I knew what I was up against on our 1st climb from Boise. The climb into Stanley was a doozie!

    the flattest route would be I-5 to twin falls and 93 straight to chalis
