The advantages of residency is you can stay in Spain for more than 3 months at a time, I have heard of a couple of people who did not have residency who over stayed the permitted 3 months and were fined, therefore if you have residency you can stay over the 3 months. As regards coming into Spain on your residency card you get in the EU passport lane and show your passport and residency card at the same time and they don't stamp your passport, and the same when you leave. I have been back too and from the UK without any problem. With a residency card even if you did have your passport stamped once they see your residency card they just wave you through. I can't really see of any other advantages other than you can stay longer legally. The other advantage is renting properties for 6 months or over is you need a residency card (NI number on it). Although there are other ways to do deals with landlords on airbnb without a residency card
Hope that helps, let me know if you have any more questions
