I work as a Sr. Information Officer at a Manufacturing company.
Currently, I'm looking to compare Dell PowerProtect DD (Data Domain) vs NetApp FAS Series.
Also, if possible, I'm looking to compare how they are both compared to Pure Storage.
Can you please share your inputs?

I think they are different types of storage for different purposes.
If you are looking for a storage where to put backups data you can think Data Domain is the perfect choice because it is its main use (most or all the backup softwares have plugins in ordere to manage data domains).
If you are looking for a primary storage (where to put your servers' data) then you can look to Netapp FAS and Purestorage.
The latter are flash natives so it's simpler to manage and configure. If you look at the Netapp FAS you can also choose storages with HDDs with less performance (and a cheaper price).
@Dhruba Roy, your question conflates very different kinds of storage.
PowerProtect DD is Dell's latest version of Data Domain. It is ONLY useful as target storage for backups. Nothing else, not even archiving. If that is what you want, it does what it's supposed to do. Albeit, it's a bit pricey and underperforming.
There are much faster, cheaper, and more advanced backup target storage. Especially when measuring restore performance. I would suggest you take a hard look at a variety of backup target storage vendors including, Infinidat InfiniGuard, ExaGrid, Quantum, StorONE, iXsystems, and many more. Most backup target storage is all HDD although some are hybrid SSD and HDD.
NetApp FAS is a general-purpose storage system for blocks and files. It can be all HDD, hybrid HDD and SSD, or all SSD (all-flash FAS or AFF). It's a solid all around storage system with NetApp pioneered capabilities, but expensive as a backup storage target.
Pure Storage FlashArray//X or //C are block all-flash storage arrays. Their FlashBlades are all flash file and object storage systems. Good performers but overkill and way too expensive for backup target storage.
I think you need to define what it is you really need. Of the 3 vendors you asked about, I am going to repeat myself, PowerProtect DD is ONLY useful as a target storage for backups. The other two can do so, but are really not priced nor designed specifically for backup target storage.
If general purpose storage is what you need NetApp and PureStorage are good possibilities among many others.
I'm planning to renew my Data Domain solution and I want to compare it with other products.
I use it for secondary storage of my backup and also for file sharing (SMB, CIFS).
What alternative products would you recommend?
I recommend Exagrid.
It is fast not only in the backup mode like DD but in recovery too. It keeps half of the capacity without dedup (Landing zone), which makes recovery of the last few backups really fast without the need to rehydrate fragmented data.
This is the reason why most backup solutions based on HDD, suffer low performance and require SSD's. Not that the Exagrid. Even the smallest box is able to fill 10Gb pipe in both directions.
If nondisruptive operations or FC or VTL is not your focus and a single controller solution is OK for you, I recommend trying it.
