There is no 'better' repository : each one compile gpe when they have time. You could have both repository ; apt is smart : it gets only the more recent one ! For now Cobb has compiled the last gpe, see instructions for repo : http://www.cobb.uk.net/770/ But I have a problem upgrading gpe-calendar & gpe-contacts : there is a package dependancy error (libgpevtype0). gpe-todo/filemanager/timesheet are OK.
