It's starting to come down to kinematics, travel and leverage ratio more then anything these days. We're starting to see the geometry get dialed into minute changes from one intended riding style/type to another. Before too long, I think you'll see the difference between trail and enduro bikes come down to .5 - 1 degree of HTA and 10mm or so in chainstay length.
It's the amount of travel and how progressive the frame is that's starting to define the categories. Shorter travel frames (and shorter stroke shocks) make it easier to compress the suspension and access the pre-load of the air (or coil) spring. This helps more riders access the playful nature of these short travel rigs that have what we used to perceive as big travel bike geo. On the heavier hitting bikes, you have to put more energy into them to get the same pop and energy out of them. This allows you to ride bigger terrain with control, but also leads to a feeling of not coming alive until they are at speed and have energy being thrown into them.
This is why you absolutely must demo the bikes. Geo charts and spec numbers aren't telling the story any more. These days it's about what you intend to do with the bike and what your riding style is. That is the lens you must use while demo'ing to make sure you get the right tool for the job you intend to do. From there, you narrow it down to a few bikes that fit your style and desires, and chose the one that you like the best and fits your body the best.
For example... The new ripley is a great bike, as is the new hightower. However when someone tells me they are comparing these two, my first thought is that if you're looking at the ripley, then you should be looking at the tb4 instead of the ht2. Not that the HT2 isn't the right choice, but they will run out of capacity and feel at home in different terrain meaning that to me, your first step is deciding what your ride fantasy is. Is it one bike to do everything from park days, to shuttle days, to trail/xc pedal days and a few enduro races? Then HT2 or ripmo. If you picture more xc/trail days and some xc races thrown in, then tb4 or ripley.
The sight may be qualified for something in the middle, but I haven't ridden one of those yet so I can't say.
