The buses are the buses are the buses. They are going to be good and bad at every single resort.
The value resorts have actual ques that you stand in, they do not have cover in the lines.
The moderate and deluxe have covered stops but do not have ques so (pre-Covid) it could be a free for all getting on the bus. I've read reports that during Covid some of the deluxe resorts have ques but can't verify that. All the CBR, POR and CSR (moderates) have multiple bus stops. YC/BC share buses most of the time, they stop at YC first then BC. Swan/Dolphin share buses, they stop at Swan first then Dolphin.
CBR has the skyliner. I think Pop does or if it doesn't you can walk to AoA and catch it. Pre-Covid the skyliner resorts had buses coming less often for Epcot/HS because you could use the skyliner.
Personally, I would not pick a resort because of antidotal bus service. I would pick the resort I want to stay at, period. Having said that, I no longer stay in monorail resorts because when the monorail is running it's normal schedule, it's the only option to get to Epcot and I'm not a fan of it, I'd actually rather take a bus.
