Longer paths definitely, increased jitter probably, increased latency
probably, increased loss possibly.

C&W obviously have to have a lot of peering as well, since it's all they
have to sell to their customers.  However, their peering tends to be
limited to a small number of peers to whom they have large connections,
whereas Exodus had a large number of peers to whom they had medium-sized
connections.  So the average hop-count and as-path length for the Internet
as a whole are both increased by this action, and nearly all paths
increase in length for Exodus customers.  So yes, Exodus customers are the
big losers in the wake of this.
