I'll say this, it's a hell of a lot more fun to create characters for and write an adventure for than 3E was, particularly the latter part. I love to create unique monsters, and I love to follow the rules, and in 3.XE, this was the path to PAIN AND SUFFERING, as I spent two hours working up some beast my players would fight once, think was cool, and never see again. In 4E, I just either take an extant monster and file the serial numbers off with the DMG's clear blessing, or I use the DMG to whip together the numbers I should be looking for and then base the monster on that.
