Well if you agree that Alexandrov is at least slightly better than Starshinov in an all time sense (read my entire bio and it's almost impossible to argue otherwise) and you take credence in the fact that his domestic scoring totals and per game % was even better than Firsov (they are), I'd say that Benny is a pretty damn good 2nd line offensive player.
Bowie, again, offensively speaking is one of the better 2nd line scoring options as a C. A Vs2 look inside how dominant he was among his peers puts him at 141.7 over his best 7 years, and when considering the average length of career was much shorter over the first 2 decades of the 1900's, stands as quite an insane average. Obviously context matters, and 1900 to 1908 is not the same as even 1910 to 1920 but even if you want to look at Bowie's 3 toughest years in terms of competition with Vs2, he scored 100 (06 ECHA) 100 (07 ECHA) and 111 (08 ECHA), where he was likely past his prime for that era of hockey, aged 26-28.
And there is no damning evidence that the Russians, or Bowie are poor defensive players. In fact Loktev was praised multiple times, for his work without the puck (bio) while playing an unusually selfless and physical game. I'd say Alexandrov is the weakest (and that is based on one single quote in his bio) but none of them should be confused with Bill Cowley
I think the gap between Yakushev and Alexandrov is quite smaller than people realize and Alexandrov is better than Starshinov in an all time sense. Both of those guys are consistent 1st or 2nd line players, ever year in the ATD.
