For me, I like it but I cannot point why. Maybe due to sentimentality.
However, I also like Cocktails, and there FS at least sometimes is too delicate.
I believe, most of the hype comes from the hype itself, like a self fulfilling thing. People see the values, FS gets traded in Auctions, and wants to take part. Also, having a series like the ECS does usually trigger the urge to hoard and collect. Both does happen in EU recently, fueled by the US market (we all have a look at what’s happening there in reddit or Facebook groups).
However, if the new ECS is priced over 70€ I consider it too expensive, as the vintage release this year has 1 year more and more ABV, and sets the bar for comparison.
