I prefer the Morgans to the Braxtons. I always felt the Braxtons were forced on us and we were going to be made to like them by them being at the center of everthing therefore no escaping them. I always felt the 3 core Braxtons were targeted at the 'he's fit, best show ever' twitter brigade that they comprimised every other character on the show, ignoring most of them and in some cases just getting rid of them (Angelo and Liam) purely for not being a Braxton and therefore deemed not as popular because they just assumed that the Braxtons were the best thing to ever happen to the show, especially Brax who i just found arrogant and insufferable. I also hated characters connected to them; Ricky, Phoebe, Ash, Charlie (who was one of my favourites until they paired her with Brax), Bianca, Henri, Sasha the list goes on. There was just no let up from them and it spoilt the show (the same way it did when Martha dominated absolutely everything a few years before).
The Morgans don't dominate the show. I'll admit i do find myself a little confused by their witness protection plot at times and it does feel like its dragging on a bit but i'd rather that than a flimsy 'everythings fine now, lets never mention it again'. Tori is probably my favourite, she works great with Nate and Duncan and Brody is coming into his own now as well. I had doubts about Justin, he seemed like a carbon copy of Brax but having seen more of him i'd say he's a nicer version and that makes him more endearing. He still has a few annoying traits but i can tolerate him in a way i couldn't tolerate Brax. Mason is the weakest, but i put that down to him being the least developed (and pairing him with terminally annoying Evie was never going to help). They are a bit isolated at the minute so that needs working on, but with the introduction of Hope and Raffy as well who i really like i find myself more invested in the Morgans than i ever was with any of the Braxtons (although i did like Heath, just not with Bianca who unfortunately he seemed surgically attached to in the end). Even Phoebe seems to work better with them. She's slowly been going up in my estimation for a while and don't find her anywhere near as annoying as i used to, she's like a new character around the Morgans than she was with Kyle and Ash. I'll never love them like i did the Sutherlands but i do see more potential in them than i originally gave them credit for.
