Mmm... Both have additional content (I.E Games) that have to be obtained...
On ID, I read the food and home background are customizable if you have a phone to connect to.
I think 3 figures for Tama-Go equal the the price of a cheap phone or IR-Adapter for ID file transfers.
The ID has Color Screen and a clear cut layout of how to get characters. (Care Misses)
People are still confused how to do basic things like Discipline Tama-Go. (Are experimenting how to get certain characters.)
Looks wise the ID is cleaner, though the faceplate is not changeable.
However the jewel design is nice enough I do not think changing it is necessary.
Also I hear the Tama-Go screen scratches easy... the ID screen is inset and does not.
ID's are MUCH smaller compared to Tama-Go's [image from

Also ID's come in similar (or more) colors to Tama-Go. I am not sure about Black.
I would probably save up for an ID. (I have neither ID nor Tama-Go.)
Good Luck with whichever you choose Fish. ^^;;
