Wonderwall is good, but it isn't in my ten favorite Oasis songs, and might not even be in my top 20, if I
bothered to try to make any decisions about that. It's always seemed a bit bland to me.
I've noticed that journalists/critics differ a lot on what they consider the band's best songs. (The same is true for fans, of course.) Out of curiosity, I looked at a lot of magazine and newspaper lists of their best songs last night, and despite how successful Wonderwall was, there seemed to be as many lists leaving it out of the top 10 as including it, and it didn't always make the top 20.
We all have different taste, and IMO those journalists having very different favorites - picking so many different Oasis songs they consider the band's ten best - helps explain their wide appeal.
I'd posted those two concert videos of Cigarettes & Alcohol mainly to show the crowd response, 29 years ago and now.
I posted my favorite 10 Oasis songs earlier, in another reply to you.
