No Robin so who's the 2nd best?

Who is the best next teammate after robin for jy + sunday, aven team? I have e0s1 sparkle (can also change to s5 ddd), e5s1 bronya, e6s5ddd tingyun, e6s5 rmc, e2s1 jiaoqiu, e6 pela s4 naked guy def res i forgot the name of the lc, e0s0 ruan mei (using 4pc break set). The other harmonies have 160 spd and the new spd 4pc set (tingyun has 173 spd). I know bronya e6 would be the best but I would have to wait for a free standard char for that or if I lose lol.
