basic vs C memory availability

Hi all, New guy here. Have searched 'advantage', armbasic vs makeitc, trying to figure out which is better (more program space/ram!?) to program in. I realize that basic is compiled so it would have a smaller footprint [than interp] - but does it load unneeded functions? OOPS - a second question. qu...
