Whereas, for me, in my limited experience, it's the other way around. Yet I'm told they're the same (with different distances), so approaching it that way seems to be slowly helping.
In my equally limited experience, aikido throws are much easier to apply than judo throws, if you get it all right, and assuming Uke delivers honest attacks. Judo throws are more difficult as they require to twist the body and knees in not so natural angles, but I would say they are more efficient against an uke who is not delivering honest attacks. I always reserve the right to apply an Ogoshi or an Uchi Mata in such cases.
