Depends on the man of renown. Gents who were smoking 30 years ago will talk about how the quality of tobacco went down at that time and the products from the '90's onward were not at the same level as earlier.I keep on hearing from the men of renown, that we are currently living in the greatest age pipe tobacco has ever seen.
And tobacco blends are definitely undergoing changes, like mixing orange Virginia into red Virginia blends to give them more flavor due to a drop in the quality of reds, subbing out Perique with dark fired, subbing out Virginias with cheaper grades, etc that's been happening over the past several years.
All that said, some really outstanding blends are being produced by smart blenders who know how to work with the materials they have, like SPC Hogshead, a remarkable blend.
There are certainly a lot more blends to choose from than were available when I started smoking in the early '70's. But those tobaccos were by and large smoother and more lush right out the gate.
And there's no way to experience them, since a 40 to 50 year old tin of celebrated "whatsis" isn't going to be much like it was when new, no matter how much money you throw at it. Hopefully you'll like whatever it has turned into.
The point is, if you're happy with your smokes, you're happy with your smokes, and your golden age is now. It's a personal thing.
