gnumeric or oocalc

Hi all
       My intention is not to start a flamewar but to get opinions on
which spreadsheet software is better? While having choice is better, I
would prefer to start with one and stick to it if possible. In
particular I am looking for

1) things which can be done in one but cant be done in another?

2) Which is better compatible with microsoft excel?

3) which requires more memory, speed, other performance aspects?

4) which is being actively developed and has good documentation?

5) Any better spreadsheet programs out there which I have not looked at?

6) Enable some sort of scripting along with gui?

thanks for the answers
