The 2nd one for 3.5 is the one which has most in common with the 4th edition one (including some early player roles but not all of them).Has a look at 3.5 dmg recently. Its not to bad. 2E one is decent as well along with 4E. Do they recall 3.0 atm.
The 4E one just has many nice features like Page 42 which has the answer to everything (at least when it comes to improvising), several ways to give non combat XP explained, makes it relatively easy to understand the monster math and encounter building etc.
