Now if you do know which JTAG would be good to try, e.g. this one or this one, it would save me something like the serial CH341 hassle.  |
Very OT
The important part of doing JTAG work is really the software. You need a software suite to debug the system you want to work on.
On the open source side, there is OpenOCD, but it's pretty raw and you really need to be a pro to use it.
Segger has a nice cheap EDU version of their JLink adapater and it has some nice software. That's what I think I would recommend if you are new to JTAG:

Make sure the SoC you want to talk to is actually supported too:

Xilinx also has some good adapters and software, but they good units are not cheap.
Those adapters you linked to seem to be specific to Atmega chips. Are you sure that's what you need? I have no experience with this particular type.
