The Paterson tank should be very good, depends upon which model as there are different sizes. The Paterson reels are not as user friendly as the Jobo reels, but they do work well.
The stainless steel tank and reel(s) are usually quite good, but if the reel has been dropped or badly twisted, they can be a bit hard to load the film on to them. Stainless tanks, I've had two different ones, both leaked around the lid no matter what I did. That said, both stainless tanks were never a problem.
Jobo equipment is really very good, it must be as so much of it has been used by professional and amateur photographers all around the world.
Think of Jobo as a film and paper processing system, similar to Canon, Nikon, Pentax cameras etc. as a photographic film exposure system.
The 1510 is the smallest of them and is perfect for a single roll of 35mm film. You can build the 1510 into a larger tank with the addition of the 1530 extension module. This extension module holds 3 35mm rolls of film. This combination is called a 1540. The system is 15 and the next two numbers denote the number of 35mm films the combination or single tank can develop.
A Jobo 1520 is possibly a better choice, it develops 2 rolls of 35mm or 1 roll of 35mm, your choice. But it can also develop 1 or 2 rolls of 120 film if in the future you purchase a medium format camera.
You can join a 1520 tank with a 1530 module which will allow you to develop 5 rolls of 35mm film. Mixing and matching various parts of the Jobo system can be handy further down the track.
The Jobo system as far as I know, uses less developer than any other system, so efficiency of chemistry is the best.
As it seems that you are a complete beginner with film, you will need to find from somewhere some old film that allows you to practice loading onto the reel. Doing it in the dark the very first time with an exposed film that is precious to you, is probably not a great idea.
Even if you buy a super cheap roll of film of any length 12 exposures, 24 exposures or 36 exposures then just pull the film out of the cassette and practice loading onto the reel until you can do it with your eyes closed.
Good luck and do not hesitate to ask questions, no matter how silly they seem.
