I agree with everything you say and would beg anyone interested in Shostakovich 4 to listen to Kondrashin. Chalk and cheese comes to mind!
Petrenko's Shostakovich - overrated, overexposed and over here! (to coin a phrase!).
Incidentally the Berglund Shostakovich 5, 6, 7, 11 are now on ICON at bargain price with lots of other goodies including a superb Nielsen 5.
