Is SEGGER J-Link the best debugger probe for ARM Cortex debugging?

SEGGER J-Link’s are probably the most widely used line of debugger probes available today, at least within the world of ARM, and in particular for ARM Cortex-M devices like STM32 or Kinetis. SEGGER claims to have shipped over 250.000 JTAG probes over the years. I cannot verify if this is true or not, but most professional engineering teams I have met doing STM32 development are using the SEGGER J-Link for example, and so I see no reason to question that figure.

I have even heard the J-Link name been used synonymous to a debugger probe in general (from any vendor) multiple times. As such, SEGGER has almost succeeded in getting the J-Link name being the industry standard reference, much like Google have managed to get its company name being equal to do an internet search in general (“to google something”). So what about these SEGGER debugger probes anyway?
