Are chesstempo tactics easier?


In my experience:
1) You tend to get served a wider range of puzzles here.
2) Chess Tempo tends to give you more lower rated puzzles so you get more right, but when you fail one, it is quite penal.
3) Chess Tempo has different modes. In standard mode, you can think all day, and it won't affect the rating.
4) The way they are rated is quite different, and ratings are not comparable between the sites.
