The ease at which you can create your own campaigns for Facebook ads as well as being able use other tools like Instagram (which I haven't used).
Also having multiple people in charge/ownership over all aspects helps keep everything organized! Nothing really bad about it but there are some minor bugs here or things not working correctly sometimes when using certain features within ou will's platform - nothing major though just something small every now & then haha :) Keep up what u're doing guys. It makes my job so much easier!!
