Not _all_ providers listed on LEB are unreliable or unprofessional. My favourite VPS provider is one I found on LEB. They have fantastic routes to mainland China, which means I get ping times of ~85ms vs. at least 250ms with Digital Ocean.
In the past I used A2 Hosting and had excellent service. I might just go back with them as it takes some time to validate a new host. So far I'm been recommend Rackspace if you want top notice support and require business class support.
