few strong links in Europe and specially UK are: COGENT, LEVEL3, C&W,TELEFONICA
COGENT "win" most of our US links to Europe even better than LEVEL3,
but i would not be surprise if LEVEL3 win most of the links to the UK.
for sprintlink, from Caribbean C&W goes to sprintlink Miami and from
there to telefnoica even though there's a path through cogent/LEVEL3.
in terms of connectivity inside telefonica i am not happy with, alot
of latency for too many places, and alot of failures around Spain(i
assume telefonica is spanish)
C&W is very strong in UK, as well as LEVEL3 and cogent. but this is
not enough to come to any conclusion, so i would start by analyzing ip
scopes where most of the European clients are connecting from and run
some BGP queries and traces.
and checking up sprintlink peering to differenet london locations.

hope it's not too vague and it gives you anything useful,
