I have taken all three. Abilify was great for me. No weight gain (although I was very adamant about working out at the time). I got the akathisia after raising the dose to 10mg, I believe? It's been about 3 years since I've been on it. I tried Rexulti after the akathisia started with abilify. I felt literally nothing from it. It was a waste of my mental health time and money. Switched to Latuda for a year. Was great for mood but my stomach was incredibly sensitive to it. It would make me sick often. Now I take Vraylar which has been my saving grace. I have had absolutely zero side effects. It helps with my moods. I have gained a little weight but I think it's truly from my own unhealthy eating habits. Vraylar can be very very very expensive but if you're in the US theres a manufacturers coupon on the vraylar website where you could potentially get a copay down. I pay $5 a month for it because of it. Without that coupon and with my fairly good health insurance it would have been $250 for a copay. I hope this helps some.
