I've heard this a lot.
In fact I heard it so much initially that I went out and bought a 4000 to try. I really wanted the 3000 but there were none in. I got the natural wrapper and that may have been the mistake.
I only made it about halfway through and decided not to finish it. The flavor was pretty good and consistent and this is why I wasn't impressed. I guess I was expecting the flavor to be a bit more complicated but it was just plain Jane all the same till I snuffed it. I recently picked up some delicias natural again for a good price so I'll give them another go round in a month or so once they've rested but at this point I prefer the Torano silvers any day, which I've always found for cheaper.
That's just me, and I'm completely willing to change my opinion if I try some more, I'm anxious to try some of the maduro but not till people stop snapping them up for nearly retail 😉 😃
Cheers.
