On Spec - higher profile/lower profile match Champ/League 1?

[bigrob]

On Sat 15th I need to choose between 3 matches - all on spec.

Championship - Huddersfield vs Blackburn
League 1 - Sheff Utd vs Chesterfield or Barnsley vs Burton Albion.

So would you go for the Championship match or the League 1 higher profile match (Sheff Utd game) or the lower profile (Barnsley game) and why?

Personally Sheff Utd v Chesterfield.

Local derby and Nigel Adkin's first game in charge of United.
