Star Spangled Breaker has slightly different lyrics and the last best album re-recorded four old songs (Nadirecur, love tripper, わすれな草 and バックストリートチルドレン). Also noteworthy that it included the hard-to-find-live-limited version of Star[K]night.

i could be wrong but i think the whole first disc on clowns was re-recorded, and those four were additionally re-arranged. There's a noticable lot of guitar parts that just weren't in earlier versions of the tracks, unless they were recorded originally & never used. + this is just IMO but Yomi's voice here really doesn't sound like it did in '01-'06.
iirc the intro part to Believe on the second disc is also slightly different, Yomi sings different notes on Varuna, & there's other small changes like that which make it sound like the second disc's new recordings too.
But the last 4 tracks are afaik straight rips of their early release, and so is every track but Star Spangled Breaker off the other two best-ofs.
