Scruff allows you to sort by the type of guys that they're into(not just the tribe you/they are part of) it is way more helpful because it allows you to sort and message people who like guys in your body or interest type rather than wasting all day messaging people who are only into guys that aren't at all your body type. This saves tons of time by allowing you to filter to only guys that might actually be interested in you....I mean why spend all day talking to someone only into bears if you're a twink(or vice versa) with no chance of actually meeting because the other person isn't into guys like you but you have no way of knowing that because grindr doesn't have a button for type of guys you're/they're into on the profile settings when they could easily make that listable/sortable information!
