You trade the popularity worldwide for the local clasic atmosphere. Is one or the other not both.
I will always choose the local atmosphere.
Well, the best version is when you can combine it.
Some clubs do it perfectly - Borussia Dortmund first comes to mind.
Naturally, when you become global more people want tickets - so the home atmosphere isn't the greatest.
I was actually negatively surprised when I first visited Anfield - and I got seats on the Kop. It was also Gerrard's farewell - other than a great YNWA, the atmosphere was underwhelming.
Then again, we did get spanked by Palace at home in a terrible season..
