Hi!
I've put together instructions how to connect ULINK2 to ST's discovery board: e.pavlin.si/.../

"Debuging from uVision with STlink is not the same as with ULINK2."
being better is also different.
I think not having the same experience may not be sufficient to justify moving to a different tool.
Andrew is right: if you think stlink is very limited, you should be able to articulate the limitations and how they could be addressed by moving to ulink.
