AGP is better because it can handle the data much faster then the PCI slot can.
AGP is based on PCI, but is designed especially for the throughput demands of 3-D graphics. Rather than using the PCI bus for graphics data, AGP introduces a dedicated point-to-point channel so that the graphics controller can directly access main memory. The AGP channel is 32 bits wide and runs at 66 MHz. This translates into a total bandwidth of 266 MBps , as opposed to the PCI bandwidth of 133 MBps. AGP also supports two optional faster modes, with throughputs of 533 MBps and 1.07 GBps. In addition, AGP allows 3-D textures to be stored in main memory rather than video memory.

For normal office use PCI.  A word processor, spreadsheet, etc have no need for AGP.

For gaming use AGP (that's it main purpose in life) and only if your games support AGP.

Well, AGP is the way to go no matter what especially if money is no object.  Sure why not?!  And PCI is older technology.  If money were an object then I would agree with Dbrunton, but according to your question you say if given no cost concerns at all...  On that note, go the route of AGP.
