Especially the 68020 compatible ones. 68020 is one of the reasons people got excited about RISC, whereas the 386 architecture can be made to go fast more easily (but still not as easy as RISC). Of course the 386 is more ugly than a 68020 from a user mode programming point of view, and the 16 bit Intels were much, much worse.
