So last weekend I bought a bottle of ER10 at Holiday Wine Cellar, w/ their stamp of 'we selected this barrel'.

Today at Bevmo I saw their hand selected bottle. Having bought something else I decided to pass.

Would there be a massive taste difference between the two? Unfortunately the Bevmo bottle is $10 more, so I was discouraged from buying it (and the recent Bourbon Madness that's overcome me).
