It'll be a matter of personal taste, preference and priorities.
But in the situation of the OP ($10 difference between AA and BA fares), if I were to ask myself the question "Would you give up 75% of your miles to get the BA service?", the answer would be an unhesitating "Yes".
[Edited to add:] I have, in the recent past, been threatened by other FT'ers with having my mouth washed out with soap for daring to suggest that the pursuit of miles might not be the absolute number one priority when making travel choices. So I now don flameproof clothing and wait.
