they are both very user friendly and easy to use but I prefer the Firestick, even though I've had 2 die on me in Thailand, which I think is due to the hot and humid climate. Check out the reviews on YouTube for both makes before you finally decide to buy one.
get online with your Firestick, download the respective App for your VPN which you find in the App store, once downloaded, install and follow the login instructions, super easy.
I paid a Sinsod of cash and gold, the same amount as my wife's younger sister and brother-in-law, after the wedding and everyone had left, mum and dad wanted to chat privately with the wife and I and they gave it all back to us to start of life together. I assume they did that to the younger sister and brother-in-law too. Don't believe all the naysayers and BS monger's,. Whatever you decide to do, the most important advice I can give you is that you reconcile the whole Sinsod issue in your mind and heart or it will eat away at you and your future wife's relationship. The Sinsod is Thai culture.
