    I see no practical differences in actual usage with appropriate times between rotary processing and tray (or other intermittent agitation methods). If I'm doing something more in the vein of actual compensation it's with extreme minimal agitation (semi-stand) and that's a whole other ball of wax.

    Use whatever works for you. There is no magic bullet.

    My problem with this device is that it takes too little chemistry which negated the use of highly diluted developers whichai use frequently.

    Peter, you know perfectly what I meant in my post, what Film Development Cookbook explains.

    Reduced agitation is a resource that trays have and rotary not, cutting time in the rotary is not the same by far.

    In the tray you can make all, from continuous agitation to stand, with all the flavours in middle. I case you make semi-stand or stand ("extreme minimal agitation") the tray has an advantage as it is not prone to provocate bromide drags so any developer can be used with also no developer oxidation problems.

    Using a Paper Safe as a tray makes it daylight convenient.

    I use rotary for color film, and I'll use it in the future also for RA-4 in the ATL 2500.

    I use a Jobo and 3005 drum. The drums are still available new and represent an excellent value based on used market prices.

    Some people like tray processing, I never warmed to it.
    If you're not going to use trays, save yourself time and money and bite the bullet. Get a Jobo 3005.
    It's an expensive purchase at first, but it will last years, the learning curve is short, and is just about idiot-proof (ask me how I know).

    Trays or Unicolor drum (paper drum) is what I've used, and I'm notoriously lazy.

    I steal time at 1/125th of a second, so I don't consider my photography to be Fine Art as much as it is petty larceny.
    I'm not OCD. I'm CDO which is alphabetically correct.

    Well no, you can't do rotary development . Regardless, the results are basically the same and we can chose our tools as needed to actually make work. I'll leave it at that.

    Bryan, with trays you can do continuous agitation which is rotary without drawbacks. Compared to tray with continuous agitation rotary only has the drawback of oxydizing the developer, so some developers have to be refilled in mid course, or an antioxydant has to be added.

    Developers like PMK tend to generate nasty general stain in rotary, for example.

    When I have finished the ATL 2500+ retrofit probably I'll do some rotary BW because that rotary it's fully automated processing, we have all the drum collection including both Experts, you press a button and the machine takes the right one shot doses from bottles, but if having to manually operate a CPE then I see no convenience advantage for BW rotary, what I see is oxydations.

    A Jobo is usually going to be more consistent both in agitation and temperature control in most normal circumstances. And if you need matched densities, that matters. As for all the fluff about semi-stand etc, it's a half-assed, inconsistent non-solution for people who apparently want to waste the time they could use more usefully learning how to unsharp mask instead - which will always have a greater impact on apparent sharpness.
