I haven't heard Into The Unknown, but supposedly it's dreadful, so maybe that'd go at the bottom.
You should really listen to Into the Unknown, if you've already invested time into listening to the other 15 records.
The band have pretty much disowned Into The Unknown, so I don't really think about it when I think of Bad Religion. I've youtube'd a few songs and they sound pretty dire, so I have no motivation to check it out. Maybe I will someday.
They certainly don't play any tracks from it, but the album shows a lot of the creativity the band had up their sleeve -- even if the results ended up somewhat strange. The album also resulted in the departure of two band members, which unquestionably shaped Bad Religion going forward. Of course it's not their best, but it's an important listen into Bad Religion history.
Yeah, that's a fair point, but it's hard to find the motivation to listen to an album I know I won't enjoy.
