Answer 1

Are $text_compare and $text_wishlist just numbers?
Then:

<?php if ($rev_srav) { ?>
<li <?php echo $text_compare ? '' : 'class="hidden"';?>>
    <a href="<?php echo $compare; ?>" class="dropdown-toggle"><span id="compare-total"><?php echo $text_compare; ?></span></a>
</li>
<?php } ?>
<?php if ($rev_wish) { ?>
<li <?php echo $text_wishlist ? '' : 'class="hidden"';?>>
    <a href="<?php echo $wishlist; ?>" class="dropdown-toggle"><span id="wishlist-total"><?php echo $text_wishlist; ?></span></a>
</li>
<?php } ?>

And do not forget to check the number of products and add / remove the
UPD class when adding / removing from favorites. In your case, $text_compare and $text_wishlist contain all the markup, so they will always pass the condition.
In the controller, add the $compare_count and $wishlist_count variables, which contain just the numeric values ​​of the compare and favorite counters. And add any class for , for example class="wishlist0".
Then at the style level you can hide:

.wishlist0 sup {
  display: none;
}
