Often an oracle can seem more of a mellow start and it's not always as "fixed" in terms of interpretation as tarot decks can be. Starting out with oracles can be beneficial, but one thing I've learned from experience is that reading oracles will not make it easier to learn the tarot. Sometimes diving into it and really making a commitment to learning is the best way to go.
That said, there are many nice oracles out there that work very well for readings. My first was a tarot deck, but I felt there was too much to learn and read and study and so I went over to oracles.
There are a lot of nice oracles out there that will give you profound readings. One of my personal favorites is Ciro Marchetti's Oracle of Visions. It's self-published so it costs a bit, but it also holds a much higher quality than many of the mainstream decks out there. These cards don't have messages printed on them though. If that's a preference Oracle of the Dragonfae or the aforementioned Oracle of the Shapeshifters will be more of a match(to mention a few).
Whether you choose oracles or tarot decks it still takes a lot of meticulous studying and hard work. I have nine years of working with cards behind me and still I have barely left the starter's mark. Learning the tarot is a journey, a life-long one for many, and no matter how long you work at it there will always be more to learn.
It takes tons of patience, but it will bring you a tremendous insight and so much joy and inspiration if you only let it
