One provider I have personally had a good experience with is
hostpro.com, which offers VPS services with solid performance. I have been using their services myself, and the VPS has been fast enough for the projects I run without creating unnecessary complications. What I also value is the daily backup of all services, since this gives you a recovery option if data is accidentally damaged, an update goes wrong, or the system is compromised. Their technical support is available 24/7, and the assistance is free, including help with various server-related questions.
