Overall Satisfaction with VMware ESXi
At ~98% virtualization, VMware ESXi forms the core of our server infrastructure. It's an exceptionally mature product that grows with organizational needs. In our organization it is used in two separate AD domains, each instance managed separately. One of the key features of ESXi is high availability; virtualization prevents a single hardware failure from resulting in service loss. If the hardware running ESXi fails or develops a fault condition, the virtualized server can be automatically or manually migrated to a functioning host while the fault condition is addressed. An additional layer of resilience is provided by snapshot technology; prior to making any system changes a snapshot can be taken to supplement existing backups and provide a point-in-time recovery. Snapshots also make backups less intrusive when a compatible platform is used.
- High availability/vMotion for hosted VMs is a must-have in any business. No one wants their systems to fail, knowing that the hosted systems are protected and always available is a great stress reliever.
- Load and resource balancing (with proper licensing) keeps busy servers from consuming all available resources on a given host. DRS and StorageDRS make short work of balancing workloads, I find this a must-have feature.
- There are some odd issues with VMware's virtualized network drive (VMXNET3). On occasion, after a reboot of a Windows-based VM the NIC will fail to bind properly and network access is unavailable until an admin intervenes by disabling/re-enabling the adapter. While it's possible that our environment is a contributing factor, this never happens on VMs using Intel E1000 emulation, only the paravirtual NICs.
- Logging is extensive but difficult to work with. VMware's solution is a product called Log Insight, which comes at additional cost. Fortunately this is somewhat mitigated by the extensive support documentation and robust user community, but in the heat of the moment obtaining the required detail can be a trying experience.
- We have successfully run many workloads in ESXi, from backup systems to Exchange servers. Hardware costs are predictable and easier to manage, and ESXi hosts can be introduced or retired with little to no impact to production systems, allowing for rolling hardware upgrades.
- Management time of individual staff is reduced. This is enabled by the powerful and flexible automation options in the platform.
Hyper-V is a viable solution, but in my experience the management toolkit has always been its Achilles heel. vCenter provides everything in one UI, whereas Hyper-V requires multiple tools to accomplish similar tasks. Licensing costs are higher with VMware, mostly because they can't just bake it into their operating system, but with the added cost comes top-notch support via phone or email. Hyper-V is perfectly capable, but doesn't enjoy the same wide base of community support that VMware does. ESXi is also extensible by third parties to a degree unmatched by other platforms. There's a reason many organizations feel that the ROI is worth it and invest in VMware, making it a de facto standard of sorts.

Yes
We run a 24x7x365 production operation. Knowing that someone will pick up the phone and troubleshoot a severity 1 issue is well worth the price.
Yes - In fairness the bug was with an add-in component (NSX Endpoint, formerly vShield). Nonetheless, support owned this, provided a workaround, and ultimately provided a release that addressed the initial problem.
I've previously noted that we encountered an issue with NSX Endpoint. This manifested itself as a problem in networking on individual servers - mail delivery was slow, for example - and VMware treated this with high priority. The tech walked me through a method of managing the issue we faced while the development team addressed it. The tech even followed up a month later to see if we were still facing the same problem and to ask if there was anything additional he could offer by way of support.
