This is quick because I'm running late and no time to elaborate. I don't think anyone can conclusivley say one method gives consistently better results than the other. It depends on the individual and what works best for you.

I'll put in the plug for tray development. Tanks for LF can get expensive. Trays are cheap and once you get the technique down, pretty easy. Many of the Greats, both past and present, use tray development, even for ULF sizes. I was scared of it at first but quickly became comfortable with it. Flubs can happen, like dropping a sheet, but flubs happen no matter what technique is used.

I can elaborate a little more tomorrow.
