I don't think the bus issue is all that bad (though to be fair we always have a car so we have options if we don't feel like waiting for a bus). I think the perception is awful because a: if you are amongst the first on the bus going to a park, you've gotta wait those extra stops which feels interminable because you want to go go go go GO!
b: on the way home, if you're amongst the last stops, the wait also feels interminable because once you're on property you know you have to wait up to 5 more stops before you can finally relax, which can feel brutal. Also, if you're amongst the final stops on the way TO a park, by the time a bus arrives it may be packed so you're always SRO.
But here are the tradeoffs, which might not benefit you but definitely benefits some.
a: by being close to Downtown Disney, you're also close to a lot of extra dining options. For breakfasts or the occasional "stay at home" early night dinner, I'd opt to get pickup at Wolfgang Puck Express or Earl of Sandwich versus the more limited options at Artists' Palette.
b: If you have a shopper or someone who likes to be pampered, walking/boating distance to DtD and having a spa on site is a really nice perk.
c: 2 main pools and 4 quiet pools. Those quiet pools can be heaven for grownups without kids, OR if the kids just want a quick dip before bathtime and bed without a big to do going to one of the big guys.
d: Being so close to DtD also means you're still close to a "hub" with bus access to all the other resorts. If you don't have a car but like to resort-hop, go to the different restaurants, it's extremely convenient. Congress Park is IMHO the most convenient section to stay in because of its proximity to the bus stops. A 10-minute predominately shady quiet walk (until you get to the road), and you have access to buses to every other resort in WDW. If you want to go to the Beach Club for the character breakfast one morning, instead of taking the bus to Hollywood studios (which may or may not be crowded, and you have to wait for all those other stops), only to then walk or boat from Hollywood studios to the Beach Club, you can just walk to the bus stop, and the bus to the Yacht Club (which admittedly will still probably hit the other Epcot area resorts too), should be much less crowded. Likewise, you can go to a park in the morning, take a bus to a different resort for lunch or dinner or just to snoop/shop/beat some heat, and take a bus back to DtD and walk to your room. Or go to park in the morning, go home, take a nap or a swim, gussy up and take a bus to one of the resorts with a nicer restaurant (Cali Grill, Artist Point, Shula's, etc) or one of the dinner shows without stinking like a wildebeest. At that time of night, more people will probably be going TO DtD than from, so it might not be too crowded, and when it's time to "go home," most people will be leaving DtD, not going to it, so again, the buses shouldn't be too much of an issue.
Every resort has some degree of perks that the others don't. For people who just want to be close to the parks and hit 'em commando style from open to closing, the benefits to SSR aren't always so clear, but for people who like to wind down for a vacation, like to shop or spa or resort hop or lounge, they're nice options to have.
