It can't jump to a file or folder by typing, it immediately goes to search, which 80% of the time crashes the entire thing, and it lacks a ton of other very basic features where I'm questioning if people who use it even do anything more than browsing the web with their system.
The only time Dolphin crashed on me (always) was after a recent fresh installation, which was a bug that just required me to manually create the thumbnail folder. I don't think that's even a debatable comparison.
KDE's Dolphin I use most. I haven't used a lot of others recently to really claim it to be my favorite though and I don't want to form an opinion on any that I used just for a short moment many years ago.
