Bankview is definitely an underrated hood, at least from the main stream discussions.
I think what keeps it beneath the radar is how steady it is, it's not exciting or ever the "next big thing" area - it just quietly has always been redeveloping forever, often at reasonably dense, middle-class housing products. This differs from places like Upper Mount Royal that only rebuilds mansions on an endless loop.
It's got SFHs, duplexes, walkup apartments of different vintages, all sorts of one-offs thanks to weird topography. Totally a mixed income neighbourhood with everything from fancy mansions to low-income apartments.
On the public space side it's got some great stuff too. Bankview has some of Calgary's best, oldest and only examples of road-to-park transitions. Weird and narrow street layouts and traffic calming from a few decades ago make the area calm for traffic and very little cut-through volumes despite being in the direct path of many downtown commuter routes.
Bankview's only real downside is the lack of retail, pretty much the only style of development that it doesn't have. It's really close to all the good stuff in the Beltline, while still being painfully far away from some of the basic stuff. They really should have allowed retail to grow up 17th and 14th back in the 1970s and 1980s.
