I'd take Dhrystone figures with a very large pinch of salt. Acorn machines tend to perform much better at Dhrystone than at anything else, and the Amiga version used seems to be compiled on quite a poor compiler (the comments about not performing well on 060 are a dead giveaway).
Besides, by that benchmark my 486SX/25 outperforms both at about 31000/sec.
Its not a bash the Amiga post, merely an attempt to get some arc "Facts" out there.... better than the usual "its slower than an A1200" argument/misconceptions that usually prevail.
Depends what you're doing with it. For graphics/games stuff the A1200 will mostly be faster. Sound is better as well.
