Linda, I really don't have a favorite per se. I use Nikon SLR's, but mainly because I have a slew of lenses for them. Currently I use the Nikon F4 and F5 bodies, and for digital its the D1x and Fuji S2Pro. But, I would be just as happy with a Canon for example. I go for what feels good in my hand, and is fast and easy to manipulate as far as the controls are concerned. Its really a personal choice, and one best made after spending as much time as possible with a couple candidates.
My only real stipulation other than the above is that the auto focus is very fast and accurate, the exposure and metering is well done and versatile, and the lenses available are of high quality. Lens quality speaks for itself, but I find it draws my attention away from the subject if I have to override the AE/AF all the time. I'm very happy with the F5 on these counts and find that for most of my work, and after setting the basic creative parameters I desire for the scenario (typically aperture, focus mode, etc), is to glance and check to see that its still on track and doesn't need any tweaking based on changing conditions. I can then just ride the aperture to vary depth of field as needed without worrying about the balancing the shutter speed. If I need to adjust both such as with a manual RF, I find that I usually drop the viewfinder from my eye so that I can verify the proper settings as I make them. This is also necessary since the controls are not easily placed for rapid and positive manipulation while still looking through the viewfinder, and there are no visual indications of the settings in the viewfinder either. On the F5, there is shutter speed dial perfectly placed under my thumb, and a aperture dial at my index finger position. Not only can I easily adjust them without taking my eye from the viewfinder, I also get a positive indication of the settings in the viewfinder, along with the recommended meter reading in 1/3rd steps, and they are very fast to change. This makes for very rapid assessments and changes to the technical details, while never leaving the viewfinder or your subject.
Its the speed at which you can deal with the technical details and get back to your subject that I find appealing in the SLR's, not the rate as which you can press the shutter release button and rack up the exposure count. I may spend minutes looking in a viewfinder following a subject while the focus and exposure vary widely without taking an exposure, but when the opportunity presents itself, everything technically is already dealt with. And the instant I take the shot, I am ready for a second if the situation warrants it.
So how does this fit with which SLR I find best? Any of them that allow the above, which is most of the advanced offerings from the major manufacturers. It really is a personal choice, and best if you can play with some cameras before hand. And you are correct that its about knowing your tools and learning to use them to their full potential. No matter what SLR or RF you choose if you spend the time to know it well, its advantages and limitations, you will run rings around those with better equipment who haven't taken the time to really explore their tools potential. But there is also using the correct tool for the job. Using a sledge hammer to pound a 16d nail works, but you will overwork yourself very rapidly compared to using a standard hammer no matter how well you know and understand that sledge hammer.
Sorry for being so long winded tonight (er, ah, every night 🙂 ). But the Sox won tonight, and I'm wired 😀
