I've put over 100,000 miles on my E39 M5. Still have it and drive it frequently. I find it's handling quite similar to the + suspension. And since 2014, I've also owned a P85+ and then a P85D, both with the + suspension, so I think I have very relevant experience to compare these cars.
Yes, the Teslas weigh more, but driving a non + Tesla (coils or air) and the P+ suspension is like night and day. While yes, comparing any Tesla to any other car is difficult, if someone is truly into sport sedan performance and handling, no other Tesla can come anywhere close to the sublime handing of the + suspension. Talk to any other P+ owner, and they'll tell you the same thing.
Also, the staggered rims have marginal, if any, effect on handling (I've driven both, extensively). They're really just for show/bragging rights unless you're tracking the car and pushing it to it's absolute limits of handling.
