Meh. I'll take SM Boruto over Sarada's sharingan in this case. Salad seems more of an analytical type than an actual fighter. Her sharingan can predict movement, but unless she has the speed to counter, sharingan's not gonna be very useful to her in that regard. Sakura has perfect chakra control. It's why she can use the Byukugo. There's no proof that Salad's control is on the same level. So her gaining all of Sakura's abilities is slim thus far.
Unless Sarada gains her mothers healing abilities and sharingan abilities at least as close to her father, Boruto's sage mode has more going for him with increased speed strength and sensing. Plus it looks as if the role of 'genius' in this new team will go to Boruto sense Kishi called him a prodigy already.
