Any of those would be nice. Nicer would be something adaptive, but
that's a pipe dream, I know. I'm aware of the technological limitations
of ADSL, especially the crosstalk and power limitations, how the
spectrum is divided, etc.
The difference between 10/.5 and 5.25/5.25 on the download would be
minimal (half as fast); on the upload, not so minimal (ten times
faster). But even a 'less asymmetrical' connection would be better than
a 20:1 ratio. 4:1 (with 10Mb/s aggregate) would be better than 20:1.
