The only thing is the religious war between <?= and <?php echo. I prefer the first, but Codeigniter coding rules/conventions require the second. Also, many Open Source projects won't accept pull requests using the first. Just be aware of it.

Where does CI specify to use full PHP open tags?

There's even a setting in config to use short tags, which will convert to full open tags via regex if php.ini doesn't allow them.
