@blackymarket: To avoid engaging in semantics, I'll only answer the second question, as that by default puts Jinn well above Baras.
Do you have feats that imply Jin is above Koon?
Well for starters, TPM Kenobi beat Plo Koon in a spar, and he himself is inferior to Qui-Gon. Add on that Jinn has more/better accolades, and he scales to TPM Maul as a feat, which is beyond anything Koon has. It's a pretty open/shut case.
Starkiller is comparable to pre ANH Vader, who struggled against Old Ben. RotS Anakin is confirmed as the best duelist in the trilogy essentially, and he's on par with Yoda and Sidious per G-canon. So it's a no-brainer stomp.
