Definative Sweenet Todd Cast

Im very curious, what is the general consensus on who the best players for each principal Sweeney Todd character were. So for example, of all who have ever played Sweeney in major performances, who was the best. Then again for who was the best to play Lovett. And so on and so forth. None of the choices have to be from the same version, but just the best and most definitive from any major production (OBC, 1982 version, 2005, 2007 Movie, 2012, etc.) For the sake of simplicity the core roles Im wondering about are

Sweeney Todd - Mrs. Lovett - Anthony Hope - Johanna Barker - Judge Turpin - Beadle Bamford - Adolfo Pirelli - Tobias Ragg -

Weird question but the reason I ask cus our theater is performing Sweeney and we are all in a debate about this
