i like swagger, i find him funny, although i hated his world title run because of the damn booking, he had one of the major heats i have ever seen as champion, sure he had a mix between valid heat and xpac heat, but he had the people respond to him every time he went out there...
you can't blame the title run entirely on him because the booking was horrible, like any other heel at that time the big show destroyed him time and time again and took away most of his heat, because he wasn't a credible heel after the losses. He was a credible heel early in his run after beating edge and jericho in a triple threat and after that beating randy orton, but after that two wins it was all losing for him, losing to kofi and morrison this wasn't really a problem because if you remember correctly CM Punk lost to morrison 3 times in his second title reign. the impact that hurt him the most was that he was made to look like a jackass(sid anyone?) by the big show, embarrassing him every week and they made clear that swagger didn't even had a chance against him, so it was easy to drop the title after that to misterio...
All in all, he is good in the ring, lacks charisma and personality, but nowadays what wrestler doesn't, even the main eventers lack personality like orton, so no, this isn't a really strong factor when you are evaluating Swagger, i think in the end that the kurt angle gimmick (moves and attire) hurt him more than they help him, because he isn't kurt angle and he can' talk like angle, so it reminds everyone how bad he is compared to angle...
