There are pro's and con's for both:
The Digital Rebel:
It has a higher resolution (6.3 Megapixels versus 5 Megapixels for the G5)
It has a MUCH wider selection of interchangible lenses and flashes. Almost any Autofocus lens with a Canon SLR mounting bracket will work on this camera.
The Rebel has a Faster Autofocus and wider range of shutter and ISO speeds.
If you already have a Canon Rebel SLR camera, the controls will be familiar to you.
People might mistake you for a professional photographer while you're carrying it 🙂
The G5:
It's much cheaper ($500, versus $980 for a Digital Rebel camera body with lens). If you buy the Rebel, you can also expect to spend an extra $500 on decent telephoto and wide angle lenses for it.
It's smaller and lighter than the Digital Rebel.
You can preview shots with the LCD, which is something that you can't do with a digital SLR camera.
If you already have a Canon PowerShot digital camera, the controls will be familiar to you.
It has a movie mode, which is something that digital SLR's do not have.
Of course, both cameras will probably be obsolete in five years, when even $200 digital cameras will have 6+ Megapixel resolution. Keep that in mind if you're on a tight budget.
