Seton is more suburban feeling than West District, but depending how they finish off the Market Street and Central Park it could improve quite a bit. Excluding of course the main retail areas to the west and the cookie cutter stick frame condos to the south.
I think the common thread in quality suburban urbanism examples in Calgary is the degree in which these developments are away or sheltered from their nearby car-sewer arterials.
Seton, Westman Village, West District, University District all did their best work building new main streets or tucking the majority of development away from nearby major roads. Arguably, Trinity Hills has the weirdest implementation because it's single corridor approach was more forced to merge an arterial and the main street, with somewhat mixed results depending on which section you are on. All examples, with the exception of West District and University District were further disrupted because the local connections to the arterials also became major car sewers, further pushing the walkable parts of the community away from these major streets. Seton area is particularly wild because of how many of the major roads are 6 lanes with enormous intersections and turning bays.
The implications are pretty big as it's not necessarily great this happened - effectively we are making highly walkable pockets locked away between car-dominated canyons preventing anything more urban emerging in the future and dramatically cutting off areas from each other. The scales are all car-centric, so distances are vast. Green Line and other LRT corridors have typically followed the car-sewer arterial, not the community development so transit-orientation remains limited. (Seton being an exception with the Green Line).
This is all rather unusual. Many more established big cities just upgrade their arterials to be more livable, not continue to build them as 60m-wide car sewers so that the a new walkable pocket of development can one-day be built a kilometre from them. We seemed to have stumbled onto a "have your cake and eat it too" situation - where we are as car dependent as ever in structural design and citywide organization of major corridors, but allowing more walkable pockets to development within that.
Put another way - it's like we universally decided hat an actually arterial/main street hybrid like a 18m-wide 17th Avenue SW is universally a terrible design and should never be built again. Instead we must build 4, 6 or 8 lane arterial monsters that are 40 to 60m wide. We seemed to decide that new functional main streets can only exist as a brand new stub road, essentially a little internally focused pocket corridor (e.g. Mahogany Centre SE for Westman, Market Street SE for Seton, University Ave in UD, Broadcast Ave for West District) rather than that corridor actually being a materially important street as part of the citywide system.
There's pros/cons to this approach of course - these development are great and the urban design is quiet good. But it's kind of an incremental improvement over a revolutionary one due to our inability to reform arterial road design.
