Hey there vigneshsai20,
To answer your primary question, any board you choose will suit you well provided we are yet taking about the 2 ASrock boards stated in your title as most of a board that shows a little more oomph than the other in some scenarios is negligible. The Fatal1ty board is just a board with a few more bells and whistles similar to the ROG series of boards by Asus although now they follow a much higher QC management and are dubbed to be the highest rated boards due to their higher quality of components that go into making one.
FYI, ASRock was a sister concern of Asus back in the day and they slowly broke off to form their own music. They just think adding some personality on the box will help it sell more units
😉
As per the pointer about low stocking around your area, I'm from Bangladesh and I can relate to the lack of choices in hardware when in comes to the IT industry. People or more so the importers tend to favor products which have more hype and ofc more customer feedbacks and sometimes who seems to play the loudest music at the festival. Don't worry about any of that just make sure you're offered good warranty period that the seller honors his services and that you have the option to swap it out should you choose to.
Reliability can be an issue and ASRock isn't new to it. Once they had capacitors blow up at stock clocks for their AMD boards - that doesn't mean the company is going bankrupt or shutting down but means some of its QC might've fallen through the roof. What might've happened was that the importer stocked on lower tiered boards to save costs. This is evident all over the world where Tier 1 products find their way into 1st world countries and Tier 3 and lower products come down to 3rd world countries. You can go ahead and choose a MSI, Gigabyte or Asus board for the Z97 platform and you won't be disappointed.
Lastly,
is proved by the inclusion of a link suggesting to read Newegg reviews.
The reasoning behind posting links of reviews by revered tech sites is because the hardware they have are cherry picked samples and ofc the hardware they use for tests are somewhat standardized instead of having haphazard configurations. I ended up buying an A85x-itx board that had the worst of reviews on Newegg (and was replaced by the A88x) yet I'm perfectly fine with what I'm using it for. In short Amazon, Newegg, Craigslist, Ebay reviews - big no no.
OP,
You could also check out other forums if the boards in question have any issues on the compatibility end.
