Depends if you include the 100Gb UPC / Liberty Global have.
Virgin / ntl have a long history of carrying considerably less LINX capacity than their peers, preferring to peer in more locations and have more entry and exit points on their network.
Many haven't upgraded to 100Gb to be fair. There are only about 25 100GbE ports lit on LINX. Akamai alone have 6 of them, Apple have 2, Facebook have 2, Microsoft 2.
ISP-wise BT have 2, Sky have 3, TalkTalk have none: they use 32 x 10Gb.
VM use 23 x 10Gb on the London LANs. Their network pushes >4Tb/s at peak so they must have a ton of other public exchanges, private peering and transit taking the strain.
