Is there anything better than VirtualBox?
The question is about VirtualBox
Yes, there are a lot of alternatives to VirtualBox offer different advantages, depending on specific needs. For instance, VMware Workstation and VMware Fusion have more advanced features, much better stability, and performance, especially for professional use. They could support more kinds of integrations and smoothly go through graphics-intensive applications in general. Hyper-V, from Microsoft, is also a good option, especially for the Windows environment, since this keeps tight integration with a Windows OS and ensures good performance with low overhead. It provides VMware vSphere for more advanced management or even Proxmox for more enterprise-level requirements. For the more general-purpose virtualization, VirtualBox is very well suited, but other solutions can be “better,” depending on whether your needs require specialized features, performance, or integration with particular environments.
