These are literally the only vinyls I have in my collection (I only collect CDs). I didn't have a record player at the time, but when saw them for only $3 and $4 at a garage sale or flea market or something in Quebec a few years ago, I couldn't resist.
War is a good album, it has my favourite U2 song ("New Year's Day"), but overall I think U2 never really found their own sound until
The Joshua Tree. But their best album of all is
Achtung Baby which is a 90s album. So for 80s, I would say The Cure was better, while U2 was better during the 90s. Overall, the two bands are about equal, but maybe U2's influences are a bit too obvious in their early work. They weren't trailblazing band until the late 80s or early 90s.
If I were to rank the best 80s post-punk/alternative rock bands it would be something like this:
25 The Feelies
24 Big Black
23 Mission of Burma
22 Galaxie 500
21 Minutemen
20 The Soft Boys
19 Cocteau Twins
18 Echo and the Bunnymen
17 Bauhaus
16 Sonic Youth
15 Swans
14 The Chameleons
13 The Sound
12 Wipers
11 R.E.M.
10 The Stone Roses
09 The Jesus and Mary Chain
08 The Go-Betweens
07 The Cure
06 The Fall
05 The Replacements
04 Felt
03 Pixies
02 The Smiths
01 Joy Division/New Order
Just looking at 80s output, U2 was very close, but still a notch below these bands, imo.
