Multiple SEO Plugins Beneficial or Bad Idea?

I already have Yoast SEO in place and it's embedded in nicely into our entire site (approx 56 pages/blogs), I just installed SmartCrawl last night and began thinking, is this a bad move (as we're just starting to gain organic searches in Google -- avg. 5-10+ per day), or I guess basically the question evolves to what's the best practice in my use case? Should I enable the SmartCrawl plugin, hurry up and add as much detail as I can from Yoast and then un-install Yoast, or am I even perhaps better off leaving Yoast as is and not enabling SmartCrawl? Any insights would be great!
