I’ve had a number of Macs with fusion drives (including my current i9 iMac) and they are fine for most everyone, myself included. And I’ve never had one fail.
The speed advantages of a SSD are overblown - a normal user will never notice them.
Totally untrue and inaccurate. The moment you get into a work flow that fills up the SSD size of the fusion drive, overall performance is cut by a huge margin. And this is very easy to do.
I've had fusion drives in my last 2 iMacs and now have a 2019 with SSD only and the difference really is night a day.
