Edge is the bigger star.
The better talent is subjective. I would give that to Edge, personally. Bryan is better in the ring (Edge is good, Bryan is great) but Edge is better at every other aspect of wrestling (mic skills, charisma, character, look). But it's subjective. Some may prefer Bryan, fair enough.
People underestimate how big Edge and Christian were. Any lapsed wrestling fans I talk to, online or in person, know who Edge is and what he did in the early 2000's, the feuds with the Hardy's, the initial solo heel turn. Edge was THE heel from 2004-2009, people who are just referring to him as a transitional champion who kept it warm for others are really doing him down and rewriting history. He was probably the most over heel since McMahon, his heat was absolutely insane. He was the guy they sent their top faces to, he was the guy they knew the audience wanted the faces to beat the shit out of (Edge knew this too, made no attempt to be liked and played it expertly) and whenever they attempted to supplant Edge as the top heel, as Triple H attempted in 2006 briefly, it didn't work and they had to give Edge the top role again. His feuds with Cena and Undertaker are legendary as two of the best feuds since the end of the Attitude Era.
Bryan did well as a guy in the right place at the right time, who took advantage of his indy status to get organically over with the "yes" movement but he was never at the level of star power Edge was. Edge is a bigger star.
Regarding outside wrestling, Edge was a supporting part of an ensemble piece, a very popular series and he held his own in that. A lot of people I speak to who watch it and have no interest in wrestling thought his performance was very good and that he held his own and when you play alongside actors such as Gustav Skarsgard, you get very quickly found out if you aren't up to it and he was. He was also sought out by Kelsey Grammar for that action film he did, where he was the main character. Bryan has probably a little more notoriety from Total Divas (as he's playing himself and is far more forward in the mix than Adam Copeland was in Vikings) but he is very much known as "Brie's husband" in that, Brie is definitely the star of that particular thing as the show is about women and their relationships, with women as the target audience. I don't think either really impacts a huge amount on their wrestling notoriety - I don't think people who love Vikings are suddenly going to watch wrestling because Edge was in it, nor do I think people that like the reality TV dramas of Total Divas are suddenly going to want to watch Bryan put on a wrestling clinic.
So yeah, the bigger star is clearly Edge.
