I switched from RWS to Oracle after realizing different decks work for different things. There’s a really good thread on Oracle vs Tarot that can help you decide better.
Since you’re already comfortable with RWS, you’ll probably find the transition smoother than you think. Oracle decks really do let you breathe a bit more, plusno reversed meanings to stress about or complex spreads to memorize.
For your first deck, I’d grab either Work Your Light by Rebecca Campbell or Wisdom of the Oracle by Colette Baron-Reid. Both are already linked further up the thread.
Work Your Light has this dreamy pastel artwork that just makes sense the moment you look at it. The messages are super clear and encouraging. Wisdom of the Oracle is specifically designed as a teaching deck - Colette literally made it for beginners, and the guidebook gives you multiple meanings for each card so you can develop your intuition while having backup.
The big difference you’ll notice coming from RWS is that Oracle doesn’t have that strict card structure. Each deck is totally unique. Some have 44 cards, some have 55, some have way more. The meanings are usually printed right on the cards too.
