My Trek full Sus has a Shimano Press fit. It's been pretty good all in, replaced twice in 4 years of regular use. It seems to outlast the external one on my hardtail. The full sus tends do more miles and in worse conditions. I'm not wedded to either but it wouldn't be my deciding factor on any bike.
There are different pressfit standards so saying all are cr@p is a bit meaningless. Shimano only make a PF41/BB92 design whereas others like BB30/PF30 are commonly used by others. The one to avoid is BB30 or anything that relies on a metal-to-metal of bearing to shell. I have 2 bikes with PF41 and both have been creak-free.
No, I was surprised to find I had one on a bike I had once, it was a pita the one time I needed to change it, but otherwise it was a bit of a non-issue, but if it was the only deciding factor on two bikes, I'd take the threaded one every time.
