After doing some serious research all I can do is list the pros and cons of each...
The Gmini 400:
PROS: 1)Larger screen 2)Longer battery life 3)nicer controls 4)supports Compact flash cards (and other w/adaptor) 5)If you grab the remote as well you will get an FM transmitter with a mic. (this will also save battery power on your unit)
CONS: 1)Battery is welded to unit and can only be replaced by Archos 2)the EQ function for audio playback is limited to bass and treble.
The iAudio X5:
PROS: 1)Offers a 5 band Audio EQ and preset SRS effects, etc. 2)As far as an AUDIO unit Cowon probably pays more details to sound performance juding by their mp3 players
CONS: 1)Like he gmini the batter is welded to the unit and must be replaced by Cowon 2)the screen is smaller (1.8" compared to the gmini 2.2") 3)you can NOT lose your adaptor, if you do you are in trouble because you will not be able to interface with your system or anything else for that matter 4)no second source of memory (ie: compact flash) 5)no FM radio or voice recorder 6)poor controls

It seems to me like the Archos Gmini 400 is the winner. Also, I have had the opportunity to speak with both Cowon and Archos, and it seems that the Cowon team isn't as helpful.
Good luck with your purchase.
I am looking for a PVP and am stuck between the Archos Gmini 400 and Cowon iAudio X5. I don't know which one to get. Help Please.
