Hetzner seem better than LeaseWeb up to a point: http://www.hetzner.de/en/
LeaseWeb offer 100TB for relatively little, which is great, but Hetzner have better spec servers at 10TB/month. Multiple Hetzner servers might be better choice in *some* cases. Hetzner's servers are bog-standard consumer hardware for the most part, but they've recently added two Xeon offers with ECC RAM to the main range. I've used them for two years for all sorts of things, including bursts of high throughput. It's nice when you have the 1Gbit NIC option :)
That little asterisk next to LeaseWeb's two highest bandwidth options is a bit worrisome - it says "best effort". Hetzner give 10TB with all servers and have the data centre to back it up. Using more than the limit with them puts the speed down to 10Mbit/s, but each TB is 6.90 Euros monthly. That turns out cheaper than the top LeaseWeb server, so spreading 100TB/month across a number of Hetzner servers might turn out to be more reliable than LeaseWeb.
If gaming levels of latency aren't a requirement I'd always recommend European servers anyway. I'm not sure how Hetzner keep the prices so low, but I've heard it's because of the low cost of electricity. I've spent the past week trying to find a better option for me, but I've ended up back at Hetzner. Ordering an EX S4 soon, which will be nice when I'm only used to the old EQ range.
