I think Windows shops primarily use vSphere and Hyper-V (I know others can be
used, but they aren't the majority). Linux shops use ESXi and {insert one of
dozens of other virtualization systems here}. I use ProxMox and vSphere.
ProxMox 4 moved from OpenVZ to LXC, which is supported in mainstream kernels
vs. using an ancient kernel. Oddly enough, I went from OpenVZ to Proxmox
several years ago (eight?) around version 1. I went to vSphere four or five
years ago and lately I've added ProxMox back into the mix (though not primary).
I'm a fan of auto-tiered storage. Big (compared to all flash), cheap (well,
relative to all flash) and fast (compared to spinning disks).

Interesting views… and in my opinion they are all correct to some degree. What
I mean, and was mentioned at some point, is that everyone has different
requirements.
Our requirements center around scaling (something that Ryan is pointing out
here) where for his needs and budget ESXi is the best choice possibly. Support
would be nice option to have for us but much less important as we have
expertise on staff. The other extremely important thing for us is redundancy
and fault tolerance. At the extreme, we can accept a few seconds of node
downtime should a hardware failure occur – this sets pretty aggressive demands
on a virtualized environment in my opinion. Then we are into some of the more
obvious stuff regarding multiple OS support, centralized management, backup
strategy etc
For storage design, there are several approaches from slow and bulky storage
right up to super fast, extreme IOPS storage for high transactional rates.
Most of our current expertise lies in Hyper-V and Proxmox. The Hyper-V
environment will remain untouched (mostly used in development environment) but
our Proxmox environment will be slowly migrated to Citrix Xen Server (open
source). Some of the folks involved took a look at a Citrix Xen Server and felt
the learning curve was very minimal

If you think you are going to spend more time learning ESXi vs any other
product I think you'll be surprised.
The rest of those things like dedupe, compression, design storage etc apply to
any virtualization in general and has nothing to do with the product you use.
Just to give a frame of reference I manage about 100 ESXi nodes, 8 vCenters
across 4 data centers almost 20TB of ram in everything. On top of that we run a
2000 seat VDI environment using View. The time I've spent with Prox, Xen,
Hyper-v has always lead me back to VMware as long as you have the money.

You make this statement like there aren't things to learn about
non-open-source products, which is a pretty silly argument IMO.
Knowing when to dedupe, what compression to use, design storage
strategy, optimizing IO for throughput vs latency vs price, vs bulk
storage, best performance settings for different types of hosts /
services... similar things to learn between products.
