I have used the X7 every now and again...
It seems to have good loads between Sunderland and Seaham, most people who are going to Seaham will get on X7 instead of the 60 when it is in(think it is about 5/10 mins quicker than the 60 to Seaham) and there also quite a few between Seaham and Peterlee, not quite sure about Sunderland-Peterlee or how it does South of Peterlee
