McDiesel, Since you've posted your LF desire in the analog section....I'll just say unless you're going to process your own film, & contact print or enlarge darkroom prints, i'd avoid LF. So much of the experience is tied not only the the big film, but the output.
I've worked with 4x5, 5x7, 8x10 & 4x10. You can do outstanding work with any of the formats, and as mentioned the tonal range and delicacy of contact prints is something special. If you sub out any part of the process, you're missing out on a great deal of the beauty of large format.
I'd say that "unless you're going to process your own film, & contact print or enlarge darkroom prints" I wouldn't bother shooting film of any size at all. For me the darkroom is at least half the creativity and two thirds of the fun of film photography. I love it, whereas I work in telecom as an IP network engineer for a big ISP and "drive a keyboard" all the time. The last thing on earth I want to do for a hobby or art is to spend yet more time at a #%$% computer. That said, now that I'm getting back into photography after a long break, I may end up doing SOME hybrid mode work, mainly because I can enlarge negatives up to 4x5 but not larger and I'm interested in shooting 8x10 so besides the (admittedly they can be magical as people have said, but limited size and no cropping without shrinking) chance to make 8x10 contact prints I'd be stuck.
But in a way you and everyone are right. With modern films there isn't much difference at normal print sizes. When I work in medium format I shoot either my Mamiya 645 Pro or my RZ 67 Pro II. What I do with those is sort of a simplified zone system where I have three film backs loaded with the same film. One will be for N development, one for "plus some" and one for "minus some" typically about +1.5 and -1.0 or so. Given the contrast range modern VC papers can handle with still excellent results, there's rarely if ever any real need for more than N-1 or N+1.5, at least for me. But here's another odd advantage: my 4x5 kit with camera body, filters and gel filter holder, spot meter, three lenses, dark cloth etc. is still considerably smaller and lighter than my RZ 67 kit! I've been shooting with an old Technika III which is a pretty compact camera, and my lenses are old and small, but still perfectly adequate at 4x5. There are, of course, smaller and lighter options than an RZ 67. The rotating back means the camera has to be the size of a 7x7 camera. My 645 is much smaller and lighter and very easy, virtually as easy as my 35mm gear, to shoot handheld, unlike my RZ, but that's also giving up a lot of negative size. Where I'd be hard pressed to tell the difference between a 16x20 print made from one of my 4x5 negatives and one made from an RZ 6x7 negative, I COULD tell the difference between the 4x5 and a 645 one, especially with faster films. And I tend to shoot in late afternoon into evening and even night, or in deep shade in the woods, so I typically shoot 400 film.
Also, do not dismiss the usefullness of camera movements until you've tried them. I'm not sure I have EVER taken a 4x5 shot without SOME movements, typically some tilt to keep the foreground sharp. That's actually what I miss most when shooting landscapes with the RZ. Yes there are tilt and tilt-shift lenses for MF cameras but they are pretty limited compared to even a basic view camera.
OTOH, what many have already said is also true: aside from a few very specific reasons like alternative process contact prints, the main reason is because it's just a different approach, and one that I enjoy a lot for the same general reason that I love darkroom work: it's slow and contemplative. I can be just as rushed all the time as many other modern people and it literally makes a lot of us sick, or at least less healthy than we'd be if we'd slow down. I enjoy the fact it takes me 10 minutes to take a shot. Heck, many times I've spent 10-20 minutes setting up and ended up thinking, "nah, this just doesn't work like I thought it would" and not even exposing the film. But I really studied that scene and thought about composition and exposure. That may be way more annoying than fun (like someone said it was) for some people and quite enjoyable for others.
I am not getting back into LF until I can replace my old Technika though. The thing is held together, more or less, by wire and good hopes and has more electrical tape than leather on the ancient bellows. But I do plan to replace it.
If you could find someone or a group locally that shoot LF and tag along, that might help decide if it's for you.
