WD Blue vs Seagate Barracuda, trying to choose a 2TB HDD

[Cyber Akuma]

I am rapidly running out of space on this old 300GB 15000RPM SAS drive that came with this workstation I am using as a backup PC. This drive is NOT the OS drive (That's running off of a SSD) , it's just used for storage. 
 
I have an unused Best Buy gift card, and I saw that there are several 2TB drives around $50 right now, so I figured I could just replace said SAS drive with a SATA one (and as a bonus I can remove this annoying RAID card used to interface with it that slows everything down). I looked things up and saw two models, a WD Blue and a Seagate Barracuda. Yes I know there are better drives that cost more, no I can't afford them. 
 
I was looking at these two:

https://www.bestbuy.com/site/seagate-barracuda-2tb-internal-sata-hard-drive-for-desktops/6344172.p?skuId=6344172  
 
They seem 100% identical.... except for the fact that the WD Blue is 5400 RPM instead of 7200. The drive I am going to replacing is already 15000RPM so I am already going to switching to a slower drive, but I am worried that 5400 will be a little TOO slow. 
 
That being said, I saw some sites mention that the WD Blue seems to be far more reliable than the Seagate drive, and easier to recover data (somehow?) if it dies than the Seagate. Is any of that true? Which one would you recommend out of these two? 
 
I noticed that Amazon seems to have a 7200RPM version of that WD Blue for the same price:

... but I am pretty sure I can't use my Best Buy gift card on Amazon and Best Buy doesn't seem to have that model... so that pretty much sucks for me, assuming that WD Blue are indeed better. 
 
Any opinions on this? Is the WD Better for reliability? Or would I be better off with the Seagate? Is the difference between 5400RPM and 7200RPM that noticeable? Especially coming off of a 15000RPM drive?

If you have a solid backup plan, then the reliability of a HDD doesn't matter.

AS it stands, I've used Seagate drives all my IT life and never had one die on me (sample of one, I know) but the 2TB Seagates have been a solid choice for me.

Seagate has always done well for me. But then again, so has WD. These drives are honestly very similar - Barracuda and Blue are the basic consumer versions of Seagate and WD respectively. Expect comparable performance and reliability.

for storage why not getting 4tb 5400.

slow rpm but higher density.

higher density drive have a higher bit per inch, so it doesn't require fast rotation.

The 4TB ones are all around $70 for 5400RPM models.
