Does an ileostomy allow food to digest better than a colostomy?

No, an ileostomy does not allow food to digest better than a colostomy. In fact, an ileostomy bypasses the colon entirely, so food does not pass through the colon and the colon cannot participate in the digestion process. A colostomy, on the other hand, allows food to pass through the colon, so the colon can participate in the digestion process.
