Yeah, I'm still in 4e.
I have much love for 13A, but it fills a different niche than 4e, for me. I'm a fan of a lot of things it does, but it moves back towards d20 design in a lot of ways. Spells, for example. And I'm not a fan of the odds/evens attack rolls, since it removes agency from the Fighter.
It also fully embraces TotM combat and moves away from tactical combat, which is a move away from both 3e and 4e.
It follows 4e's lead in other areas, like Recoveries and monster design, though, so I definitely think it has more in common with 4e than 5e does.
All in all, it's like a mix of 3e and 4e with narrative mechanics thrown in. Which is great, but it's not filling the same niche 4e does.
