The similarities are much bigger than their differences. Yes there are pros & cons to both Debian & Ubuntu. For example do you prefer a 2 year release cycle or a 6 month release cycle. I use both distributions in different circumstances. It is thanks to everyone who has put in an effort to Debian over the past 16 odd years that Ubuntu even exists...
P.S. Props to all the Samba, Debian, Ubuntu & all the other open source developers here... -- To unsubscribe from this list go to the following URL and read the instructions: https://lists.samba.org/mailman/options/samba
