I owned an M4, loved it but in the UK most of the time I could only get down 70% of the power which I found frustrating, I can only think of a handful of times I let loose properly with it, due to roads, weather or traffic etc.
I test drove both an S and GTS in dreadful conditions flat out and I mean foot to the floor. The handling and power delivery blew my mind. I had access to all the power, went round corners safely (and fast) and I actually got to rev it out without any loss of traction - serious engineering masterpiece. My M4 would have wheel span in anything but perfect conditions, corners were incomparable and red-lining in 3rd may have lost my license. Going sideways on the TopGear test track may look cool and be fun but not in real life with a fast approaching tree of flock of sheep... not so wise.
I loved my M4, but the 718 is so much more usable in every scenario. Clear winner for me. As good as the M4 is, not sure why you'd have both. Sell M4 and get an S, you won't regret it. Also consider financing as low residuals means some of the lowest HP/PCP's for any car vs value.
My family wagon is our X3 35D which is properly quick (up for a change in 12 months which i'm excited about as there is a lot of choice out there) so when we aren't in that i'll be having fun in my GTS
