WSJ for me has a nostalgic aspect as most of the first manga I've read is from that magazine.
Regarding the access to the mangas, it was really easier (and still is thanks to mangaplus) to read the manga from this magazine for a person who can not read japanese. Moroever, even with scans, it was a lot easier to find them for the WSJ mangas than for the others.
I think that's what made me really attached to WSJ, mainly by default I would say as for a long time I could mostly read his mangas.
Putting that aspect aside, generally the mangas in WSJ are really good imo, so I naturally pay attention to what is coming new in the magazine, a thing that I do not necesseraly do for other mags (and again, scan are difficult to find for some series as Blue Lock for example). However, I think that the WSJ is in a weird time right now, lots of new series but none of them seems to really be a big thing even if most of them are great. I think that we are in a transition period right now.
To conclude, WSJ is still on the top for me as it is the mag that I know the best, series are top quality and it is easy to have access to the chapters every week (which I think is a really important factor).
Sorry for the long post !
