Why does Juno never feel right?

I'm low Diamond on Support and I love playing Juno, by far my favorite support to play and I know she's a pretty meta hero but whenever I play her it always feels like I could be doing better on Ana/ Kiri. I think I'm better at Juno than Ana and Kiri but I always find myself swapping when I'd much prefer to play Juno. What can I do or is there anything I can do to make Juno feel just as good as the other 2 supports?
