I should let someone else voice their opinion on this as well but here goes...
My answer to that is if you want a
slightly toastier/richer beer, go for the darker kilned base malt
If a
slightly crisper/paler beer is what you crave, go with the domestic 2 row.
the differences are small. Not unnoticeable, but choosing one or the other wouldn't ruin the beer. Again, I like the Great Western NW Pale Ale malt. Brewing is all about little choices that make snowball changes in the finished beer.
Replicating beer 100% doesn't happen often from two different brewers. You can hand two people identical ingredients and recipes and you'll almost always be able to detect a difference between the two final products side by side. Processes are different from person to person. Boil Kettles have slightly different dimensions, fermentation temperature controls vary, water mineral content is is not a constant. These are just a few of the variables.
Anyway, RDWHAHB. The beer tastes great either way.
