Good Morning,
While I much prefer SS, I did use Paterson tanks and reels decades ago and found them to be OK for the most part, especially for 35mm. I did have some uneven/incomplete development near the edges of 120 film, but that may have been attributable to my agitation technique. The tanks can be somewhat fragile (I once cracked one full of solution), but the Paterson system is well-designed and, with care (proper cleaning and drying), it is very functional.
