It's a hard one, as it's rated 5B (Russian grade). From what I was told it's not a desperate route in any sense and the most technical parts are not that long or hard. The Russian grading system also takes for example altitude, length of stay on the route etc. into account, so that's one of the explanations it rated that high.
My main concerns are getting stuck up there if the weather turns bad, finding suitable camp/bivaq spots, the sometimes huge corniches and rotten rock.
Also, to choose how much gear you want to bring is difficult I think.
That said, Shchara is not an easy peak, regardless of which route you choose.
