Currently, ios has at least three features android doesn't.
Airturn compatability
A search field at the top of each playlist
iCloud synch between iOS devices.
I have iRp on my android phone and a tablet. I prefer using iRp on my iPad mini which is my primary device.
Perhaps it's just familarity, but I prefer using the ios editor.
IRp was developed for iOS first.
For the most part, using android and iOS is like shopping in two different large markets owned by the same company.
Everything is there, just not in exactly the same place in both stores.
After I make a setlist for a gig on my iPad, (I use the iPad at my gigs) I also add the playlist to my (android) phone for backup just in case the magic smoke escapes from my iPad. I like having iRp on my phone, in my pocket with me all the time.
The sounds seem pretty much the same to me (but that may depend on the device) the interfaces are similar but not the same.
I'm very happy to have iRp on all my devices.
