That really depends. If you want to connect to an IPv6-only site,
"crappy connectivity" might be better than no connectivity at all.
If you connect to a dual-stack site, crappy IPv6 might actually make
the connection a lot slower and painful than "no IPv6" - because with
"no IPv6", the clients normally fall back to IPv4 pretty quickly.
Of course this is assuming that you have halfway decent IPv4 :-)
