Opinions on Creative v Logitech please

[Mat]

I'm looking to get a set of 5.1 speakers for my iMac and I cant decide between these two sets:

Logitech Z-5500 THX® Certified 5.1 505 Watts Speakers - Retail

or

Creative GigaWorks 5.1 G550W THX® Wireless Speakers - Retail

The Creative lack optical input (from the iMac) but they do have a wireless rear speaker setup, both are roughly the same price.

Thoughts or opinions???

I think I'm going with the Logitech now anyway having read a few reviews and results of others using them with their iMacs.
Thanks
