Never used a Jobo tank, never liked them, some folks love them, some don't. From what I've read, some folks have experienced uneven development using them. I have no idea how that could be the tank's fault.
Back when ... I use a couple of diff daylight dev tanks. One is a common, square, el-cheapo Yankee tank that holds about 10 sheets of film in a plastic frame -- very easy to load in the dark. Wet and messy, but never had a problem developing with it. Just be sure you do the developing in/over a sink.
The other, my favorite, is a stainless steel tank, looks like a regular old 35-mm film development tank on steroids. It's just bigger. And the stainless steel reel/holder thingy that goes inside holds 10 or 12 sheets of 4x5, they slide in from diff points around the side of the holder and kind of spiral toward the center. Put the ss cap on and agitate just like any other ss developing tank, no spilling, no mess -- except that it is heavier. I think it is made by Nikor.
About Edwal LFN wetting agent -- never used it. Never worried about removing the film backing either -- it's gonna come off with or without a wetting agent. I always pre-soak the film with water for a minute or so before developing, gets the emulation prepped for the developer. Also removes the backing from film. Using a wetting agent before drying film is a very good idea -- don't even think about skipping it.
I am a huge fan of sodium thiosulfate based fixers for film and paper. No need for a stop bath or hypo-clear, vastly reduced wash time to achieve archival quality clearing. They also remove the magenta stain from Kodak Tmax films faster and better(?). Make your own TF-3 fixer, or buy TF-4 from Photographers Formulary.
