Flexibility is major advantage, you may easily migrate vm to other server or storageso Hardware Independence
My experience is neither is better than the other there pros/cons to each. a Virtualiised environment has a reliance on an infrastructure for example. Stand alone can allow for more flexibility - for different uses for different purposes.
Ease Administration and Management, Very Less Downtime, Easy Maintenance and Backup,Effective utilization of resources.

Performance – Physical servers have the edge2-
Cost savings – It’s a volume game3-
Disaster recovery – Easier in virtualized servers4-

Virtualization is much preferred due to following.
1 Zero downtime for HW maintenance
2.Easy Snapshots for data restoration.
3. Easy Cloning,
4.Faster setup of new server,
5..Superfast storage migrations.
6.HW efficiency.
7.Lesser carbon footprints.
Above are some of the features which makes me chose virtualization and of course are not limited to these.
One should understand that by working in virtual infrastructure we are reducing the carbon footprints. We are working towards the Green-IT, thereby reducing the green house effect. Earth will be better place if most of the things will be moved to cloud.
Cost Cutting, Easy Management, Physical space reduction,etc
1. Well isolated environment.
2. Low coast to manage upgrade and resources efficient.
3. Easy to backup restore migrate to other environments with different specifications.
4. Automatic startup sequence.
5. Included firewall into hypervisor itself.
Virtual environment pros:
1-Cuts down cost for physical hardware needed.
2- Maintenance cost for hardware goes exponentially down.
3-Management becomes centralized.
4-Easier to grow as your needs keep growing.
Cons:
1- Type 1 hyper visors ( like ESXi servers ) have less chances of failures but that's not to say that don't fail. That is why they have features like VMotion.
2- If the virtual environment fails even with the redundancies in place, then you loose more than one server. where as in physical servers / environment one hardware failure means only one machine is down.
