TIAO TUMPA v2 vs Universal JTAG Adapter V2 vs Black Flash USB?

Is it right to think that TUMPA is superset of Universal JTAG Adapter and Black Flash USB products?
I see only difference in pin-out when talk only about JTAG protocol (and device prices) for TUMPA vs Universal JTAG Adapter and same for TUMPA vs Black Flash USB when talk about serial line or JTAG/SPI/NAND flashing. May be pin-out voltage levels on Universal JTAG Adapter V2 isn't 5 V or 3.3 V, but I can't say that from tiaowiki product page.
So is anything you do with Universal JTAG Adapter or Black Flash USB also available with TUMPA?
According to http://tjtag.com/ page Universal JTAG Adapter uses FT2232H chip but official wiki doesn't say so.
For TUMPA officially stated that it uses FT2232H which communicate on High Speed USB protocol (480 MBit/s).
Seems that Universal JTAG Adapter is supported only by http://www.tiaowiki.com/w/TJTAG software package, while TUMPA is supported by OpenOCD and flashroom.
Black Flash USB Universal Flash Programme schematic has FT232H on board. Comparing FT232H with FT2232H:
http://www.ftdichip.com/Products/ICs/FT232H.htm
http://www.ftdichip.com/Products/ICs/FT2232H.htm
shown that FT2232H is like double-FT232H. But strangely Black Flash USB require different firmware to operate as flasher. Is that true? Seems that TUMPA doesn't require reprogramming in order to support all kind of protocols...
FT232H chip is used in Lite version of TUMPA as state http://www.tiaowiki.com/w/TIAO_USB_Multi_Protocol_Adapter_Lite_User%27s_Manual
So again is that right that TUMPA is superset of TUMPA Lite, Universal JTAG Adapter, and Black Flash USB?

Do you have parallel port or not? If you do not have parallel port, then you can not use universal Parallel Adapter.
Black Flash USB+ is Compatible with FlashcatUSB, this device can program all CFI compatible flash devices over JTAG and can also program SPI high-density serial flash devices. Hardware support can be added using a easy to use device script feature.
Please let us know your target CPU & Flash chips, programming interface (JTAG or SPI?) so we can help you to choose the best product for you.

From your answer I make decision that Black Flash USB+ designed to mimic another device so limited to specific software.
As you say Universal JTAG Adapter has only parallel port for interfacing, I didn't read spec carefully, and was misled by mini-USB port on PCB...
More precisely Universal JTAG Adapter uses only 74HC244 8-bit buffer http://www.nxp.com/documents/data_sheet/74HC_HCT244.pdf
We lack hardware SPI/I2C/UART support, lack data buffering in Universal JTAG Adapter, but I believe that it is possible to use it in bit bang mode, but also there are no software to perform bit bang tricks.
In general I made decision that TIAO TUMPA v2 / TUMPA Lite is superset of Universal JTAG Adapter V2 and Black Flash USB by capabilities, but later devices designed for special interfacing / mimicking to other devices and used with special purpose software.
I am EE enthusiast and look for cheap adapter to explore electrical components via SPI/I2C and to flash/debug chips/MCUs.
TIAO TUMPA v2 / TUMPA Lite based on powerful FT2232D/FT232D chips and able to do those things.

What new in V2 of Parallel Adapter?
Compare to V1, the Version 2 has the following additional features or improvements:
1: Jumper to enable Xilinx Platform Cable mode. In V1, you need to short DB25's PIN 8, 11 and 12 (using a solder iron), in V2, all you need to do is to move jumpers to different positions.
2: On board NPN transistor, so you can invert any signal as needed (e.g. nSRST).
You can config it to be a Wiggler JTAG, or a Xilinx Platform Cable, or any parallel JTAG interface!
Universal JTAG Adapter V2 supports bit-banging and is supported by all software if you set jumper for unbuffered operation.

TIAO parallel universal JTAG adapter allows you to easily configure it to be a buffered or unbuffered JTAG. With provided flexible jumper wire you can move the pin configuration easily to suit different programmers.
If you want to use the adapter in unbuffered mode, you only use the 6 x 50cm flexible cables. Do not connect USB cable to your PC in this case.
If you want to use the adapter in buffered mode, you need all the cables plus you need to connect the adapter to your PC's USB port via a USB A to Mini USB B cable. Once the USB cable is connected, the PWR LED will light.

Thank you for your effort to answer my questions!
It helps me understand product capabilities and I hope it also will help another forum visitors.
Now I am convinced to get TUMPA v2 or TUMPA Lite. Just have some questions about TUMPA v2 wiring which is asked separately..

locking this one as solved
