It’s a choice
1) VRporn is 15$-20$/month depending on sales. One subscription to access everything, throw in a huge library of VR videos. Probably VRporn’s yearly subscription is a better deal.
2) Store is more expensive, every new game will cost. But you can keep the access, get the most recent version, make suggestions and more likely to get a quicker response.
