I've had a lot of cameras over the years (there are 3 SLR cameras sitting on the desk next to my PC as I write). I don't go out the door without a camera, and during my lunch breaks I can often be found either at the nearby camera shop buying film, or at one of the nearby parks looking for things to photograph.
My first 35mm SLR was a Nikon FE, and after than I owned pretty much every F model that Nikon has made, from the F to the F5. Not so long ago I acquired a Canon A1 (the "dream" camera of my childhood, many of you can probably remember the A1 ad on the back cover of the old National Geographic magazines) and a few FD lenses. I then picked up at AE1, an FTb, and then an F1. All of these cameras work wonderfully, and I've gotten great pictures out of all of them.
Whenever I go out for the weekend, I grab my camera bag. As all of you know, pro-level SLR kits are heavy. A Canon F1, a few decent lenses and other gear, it gets to be a pain to carry. Since I don't have a car, I walk for many miles with each outing, and it isn't long before I get sore shoulders.
Not long ago I found an Olympus OM4Ti sitting at a thrift store. I knew nothing about Olympus cameras, having been both a Nikon and Canon fanboy (who would believe it?), I never considered Olympus gear to be on the same level. But I asked around about the OM4Ti, and found that no one had anything bad to say about it, and many people spoke of it in glowing, almost mythical terms. I took a closer look at it, and found it to be very compact, and very lightweight. It was a jewel of a camera, and I decided to buy it.
As I became use to the Olympus, I found it to be quite superior to the Nikon and Canon gear that I had been using. The meter in the camera is simply phenomenal, and easier to use than the sophisticated meter in my digital D300.
I quickly put together a collection of lenses for the Olympus (I love Japan for it's used camera shops and their huge collections of the common and obscure), and found the lenses to be superb quality as well.
There is no comparing the OM4ti to my Canon F1 or Nikon F3 (or F4). It is smaller and easier handling, meters better, and is sheer joy to use. I typically carry a camera body (sometimes 2) with 3 or 4 lenses. My Olympus kit weighs almost half of what my comparable Nikon or Canon kits weigh.
Before buying the Olympus, I was looking at getting a Leica M7 kit. I borrowed one from a shop owner I know, and played around with it for a week. Had I not bought the Olympus, I would have the Leica now. But I find the OM4Ti to be no less compact than the Leica, and a bit lighter in weight. I love the bright OM viewfinder, and the the variety of low-cost but high quality OM lenses. Most Leica glass is superior to the Olympus stuff, but I have a few Zuiko lenses which are astoundingly good (though not cheap).
Given the incremental increase in quality one gets with a Leica compared to the more-than-incremental difference in price, I'll stick with my Olympus for now. If the shop comes down some more on the M7, I may go with it, just for the sake of having it, but I honestly don't think it's capable of taking better pictures than my current kits.
