Well, coincidentally, I was having the same predicament. I have Oxford Spanish D 3rd edition and I was waiting for the 4th with anticipation. My current one is so battered that I need to replace it. So, in my case the answer is clear.
However, the 3rd edition has been a great help to me and I believe it is fairly current. If you don't need to change it, maybe you shouldn't.
The Collins I don't like as much as the Oxford. This is a personal opinion, of course.
I have heard that the Harrap's is rather good but it is so big that I would need twice the amount of space on my desk in order to be able to use it.
Hope this helps,
If you buy the fourth edition could you let me know what updates have been made please. Harrap's is excellent for French but I am not so impressed with their Spanish dictionary.
