Samsung Apps?

Hey guys,

So Im compiling a report at university, and I was analyzing all the App Stores.

Just wanted some of your opinions on the Samsung Apps Store (Which, I guess comes preloaded in every Samsung phone in the market)

How much of it do you guys use?
How regularly do you use it?
Are there any good or better apps than the Play Store?
What is the purpose of the Samsung Apps Store?
Do you face any issues with it? If yes, what??
Any other suggestions or feedback?

Looking forward to your replies!

Thanks in advance! :)
