I think comparison is valuable because most all information is useful but Brian is correct, they're different creatures today.
10yr 1783 is really really good if you can find it. EWB is a great mixer.
I think 1783 is one of the best values out there. It is the bar brand at The Porch where we congregate and, at $4.50 a pour .. it's the go-to when you just want a refreshing bourbon on ice without a lot of thought going into the purchase. At around $10 bucks .. it is better than many you can pay many more time for IMO.
We did find some of the old 10-year old up in Georgia and have a few bunkered. It is much better than today's "10-star" ... but ... it's all good.
Yet another value brand I can't get here in AZ.
I've tried the current versions back to back. 1783 is a more refined pour without some of the raw edges of the black label, but they are very similar.
Recently did a comparo with an older 10yr age stated 1783 with a current release 1783. No contest there, the 10yr was much better. I used to recommend the 1783 when it was a 10yr but I don't any longer. The NAS juice does seem to hold up well to water as in melting ice, just doesn't work for me as a neat sipper. I still have a number of Bourbon knowledgable friends who drink it with ice and like it as a value pour.
The 10 year version is certainly worth stocking up if you can find any.
I used to be a huge fan of EW 1783. But in the past few years I have been reaching for EW BIB and FC instead. I guess my tastes have just changed to higher proof expressions.
I think 1783 would definitely be improved by moving the proof upwards.
