Smallville classics?

So metafandom linked to an interesting post on fanfic classics , and I can't help but note that as of my posting this, no one has posted any Smallville classics yet. I was going to remedy that, but had a brain spasm: what are the Smallville "classic" stories? I mean, I'm most likely to go with something by seperis, something by thamiris or something by rivkat--I'm sure many many authors would also qualify (I could just go look at some of my old recs), but those are the ones that laid out my personal fanon. But it's hard for me to pick one or 2 stories--and I haven't really been reading in Smallville for that last 3 or 4 years, so maybe there's something new that would qualify. What do you think, SV fans on my flist?
