I have a G690BL with the non-AE 100. I've owned or used the fixed-lens GW690II as well, along with other MF RF cameras like the GS645S, Mamiya 6 and 7, and Super Ikonta A and B. Actually, I've used the Horseman VH-R as a RF camera too.
Compared to all the others except the Horseman, the G690 series is BIG. And HEAVY. It feels like a boat anchor around my neck and in my hand. Obviously, different people will have different tastes in cameras and differing tolerances for size/weight; only you can tell what's right for you. But if you've never seen one of these in the flesh, and your experience of RF cameras in the past has been with models that are compact and lightweight for their respective formats, think again. Forewarned is forearmed.
