That's a pretty sweeping statement rab. Would you care to back that up or are you just going to go around willy-nilly declaring some numbers to be more nice than others ? I think we should be told. It's a slippery slope you know. First its "oh 10 is nicer than 11" next thing you know its 4am and the police have smashed in your front door and you are in teh back of a lorry with a sack over your head being shouted at in Welsh.......
No, 11 may have a certain richness compared to ten, but is horrible as it is nearly 12 but not quite, and 12 is the best number. It is also the number of Apostles left after Judas quit (despite 1 Cor 15:5). And it's a prime number, which is bad. Ten is more satisfying all around.
