The Class 26 is not a 441 clone. Its maximum needle size is probably a #24 or #25, but a 25 might be aweful close to the feed dog hole diameter. Ask the dealer.

The Class 26 is not too heavy duty for wallets and belts as long as you use #92 thread with a #19 needle or larger. I don't know how well it nandles #69 thread and #18 needles.

The Cobra Class 26 uses the system 135 x 16 or 135 x 17 needles which have a size diameter of about 1.0 mm (0.0394 inches) while the needles for a Class 441 machine the 794 needles are 2.5 mm (0.0984 inches). 

The Cobra Class 26, is the model number not the class of the machine and is a hybrid clone similar to the Juki LS-341 a Class 341 machine. The Cobra Class 26 like the Techsew 2750 and others model designations can be confusing but all are Class 341 machines. I agree with @Wizcrafts and as a note I don't use anything smaller then V92 in any of my machines.

What is the general choice for leatherwork regarding thread? Nylon, Polyester or something else?

If the item is going to be exposed a lot to UV rays or bleach type chemicals Bonded Polyester would be the better choice. Generally other items Bonded Nylon is a good choice. I mostly use Bonded Nylon. As a note:

i) Bonded Polyester for a given thread size is a touch smaller then Bonded Nylon

ii) Darker thread colours are stiffer then light coloured threads due to the dying process

iii) I find that the 1 lb spools are better then the smaller spool sizes due to less spring memory as a result of being coiled onto the spools. 

iv) Only load up enough bobbins to complete the project. If left for more then a few days or less the bobbin thread comes off the bobbin looking like a coiled spring.

v) Always buy good quality thread.
