You don't need to convince me, I already know that. I liked the characters in Kotor 1 more but Kotor 2 was the superior game. If (and that's sadly a big if) you can deal with the bugs and the rushed ending.
That seems to be the Obsidian way: Make a better game but ruin the perception through bugs: NWN 2 was far, faaaar better than NWN 1, New Vegas was better than Fallout 3 and Kotor 2 was better than Kotor 1. But all three of them were riddled with bugs.
