You’ll be fine with 27.5, I prefer 27.5 over 29ers.
All the rides I do, mostly heavy XC/ Trail and enduro, all the people I ride with, ride 29ers, I have no problem doing anything they do and believe my bike handles better than all of their bikes and is just as fast over all kinds of terrain.
To stay on subject, Intense has a long history of making grwat bikes and have been the pioneer in lots of tech.
I ride a Turner RFX, and think you should consider other makes and get what you find the best for the riding you do.
