Both the BDI2000 and the Jeeni work well with GDB/Insight.

I'm only familiar with the ARM7TDMI, but it works fabulously!

In my experience Angel (and RDI, same thing) aren't as well supported under
GDB as the GDB remote protocol is. The Jeeni speaks RDI, the BDI2000 speaks
GDB. The BDI2000 also has a handy telnet terminal, for when you're having
trouble with GDB.

I'm only familiar with elf. It seems to be the most common format for ARM
targets. Works well.

If by "kernel" you mean Linux kernel, I have no idea as I'm not running Linux
on my target. I am able to debug our in-house RTOS quite well though. I'd
even be willing to say it works *better* than local mode because you can step
through interrupt handlers much easier.
