Balls deep

Serious question - on the 5-star selector after the end of Plan 1 between Ann/Morgana/Ryuji, my current options atm are between

A6 Ann or R0 Ryuji

Should I just get Ann to A6 asap or get Ryuji to expand roster options? My account has been giga lucky with Ann spooking me a lot (got A1 Ann in the first 20-rolls on beginner banner & she kept showing up randomly)
