Which programmer to choose for stm32: coolinkex or jlink?

Question

ARM

Good afternoon!
Here came such an ARM Cortex-M3 STM32F103C8T6 STM32 board:
www.ebay.com/itm/111297094334
As a noob, I sincerely thought that it was flashed via mini-usb)
It didn’t work out) Then I learned about programming via UART, SWD, JTAG.
The question arose - what is better to take - coolinkex (clone from di halt) or jlink (clone from ebay)?

Answer 1

For information. Time judged, everything worked out with st-link v2 and SWIM

Answer 2

If you plan to work in IAR, take a clone of J-LINK from eBay will not be a problem.
I have been working with originals and clones for five years and did not feel much difference.
In addition, J-LINK works not only with microcontrollers of the STM32 family,
but also with other ARMs from other companies. And this is a lot of microcontrollers.

Answer 3

J-Link because it is universal
