TSLS is, superficially at least, a close cousin to the output of '88/'89,in as much as it sounds like a poor B side from that era, dressed up in expensive production. But the chorus - with it's clunking melody line - is reminiscent of a '90's boy band & marks it out, for me, as one of the more detestable tracks on SC.
In terms of spirit, I'd go for LS. It's the closest to the sort of immaculate construction that echo's that of the debut. A fair amount of thought seems to have gone into the structuring of that track, in respect of the way the guitars gel with the rhythm section & lyrics &, despite being pure "70's hard rock, it seems to avoid the MOR clichés of some of the other songs.
I'd also chuck in Ride On, again in terms of spirit.
