GBLX are probably better for european users IMO. Internap aren't in the same field as they're an aggregation provider rather than direct transit, however I do find that Internap routes from the UK are rather nasty.
Level3's routing is a bit shakey as it bounces around to strange places too...

We are a UK host with a BGP4 mix of GBLX, Level 3, Globix and C&W. GBLX is far and away our favourite upstream - very clean pipe, good throughput, strong geographic reach etc. Not had any outages or indeed any issues whatsoever in the last 12 months.
Level 3 is not bad but we've seen a few issues now and again - 10min outages here, unacceptable latency for 15mins, that sort of thing. They're a big well respected network but we are moving away from them in favour of Sprint.
GBLX are a pretty good company to work with too, excellent knowledgeable account manager who can get our tricky technical questions answered. Their pricing is generally competitive relative to other Tier-1s.
