Im using samsung pay for more than a year and didn't have any problems with it. Works perfect. You can put all your bank cards, travel cards or reward cards in one place its very handy. And you get cash backs from many companies when you pay with samsung pay.
Most important you will get real phisical samsung pay contactless card and you can use it instead of using the phone. So basicaly all your cards in one card.
But just be aware that you can use only one paying service on your phone. If you using google pay at the moment you can't use samsung pay. If you deside to use samsung pay you won't be able to use google pay.
