I've only been seeing negative reports as of late, and am curious if there's anyone who is happy with their 16"?
I'm pretty happy with mine (i9, 32GB, 8GB 5500M, 1TB SSD).
I did have some weird issues with browser-tabs failing to open even though my networking was otherwise working. See

This drove me mad for a while, and I think it was related to running out of file descriptors. There are various solutions out there for changing the system limits temporarily and permanently, which I tried, but the problem "went away" even without applying the permanent fix, so I really don't know if this was the root cause. I did a complete clean install a couple of times in an attempt to fix it, which was a time-consuming hassle that undermined my confidence in the machine for a while.
Stability of Catalina was initially unimpressive but seems to be much better now (after 7 point release

)
Overall, the machine is pretty solid; performs well and is generally reliable. I'm glad I went with 32GB RAM and 1TB SSD, because I frequently end up against memory limits (using a lot of swap space) and 16GB would have really slowed me down by having to "tidy up" my workspace more often.
The new keyboard is really nice to type on, although now that I'm working from home, I'm using an external Apple keyboard (old design). Trackpad is huge and great to use - Apple still leads in this area. Speakers and microphone are very good for a laptop. Web-cam a bit underwhelming with only 720p resolution.
I haven't used this computer extensively as a mobile device due to limited movement for work and travel this year, so I can't really to speak to the "laptop experience". It is quite heavy, but I had to weigh that against having sufficient power to replace a desktop computer and having enough screen real-estate for my uses (development, productivity apps, video-editing). Battery life is OK - but nowhere near the advertised 10 hours in real-world usage (for me). 5-6 hours is more common - still much better than most Windows laptops I've used recently for the same tasks.
It gets an 8/10 from me.
