It is really unfair to take bootlegs as any sort of representation of a band.
Bootlegs are as a rule crappy and somehow generally of terrible performances.
They're never a substitute for a live performance. Pavement is certainly brave to post two entire bootlegs for the internet public to hear for free. Part of Pavement's charm has always been their unapolegetic sloppiness. Or former unapologetic sloppiness. Which just goes hand in hand with the bootleg format.
