If sasuke has two sharrinnegan ,then he at least two times much stronger. With another sharrinnegan he can get a new ability or something to control his present rinnegan ability. Though in Boruto it doesn't look like sasuke will be concentrated upon much, only Boruto and Naruto will be shown more and given more abilities. If you mean two normal rinnegan, then I think sasuke is better off with one EMS and one rinnegan as he can use both mangekyou and rinnegan powers at the same time.
