You are about to get bombarded with boutique brands..
But not from me.
The two bikes you picked are brilliant, the Anthem is far more speed and race focused than the Trance, which you already found out but i would never describe the newer Anthems as twitchy, but they are responsive bikes. Did you ride the older Anthem model or the Anthem X (the Anthem X didnt have such steep angles)
The Trance is far more laid back in terms of its nature, and with more travel it will be better at more techy and steeper terrain. I havent ridden the Trance but initial reviews are very favourable, i rode the 26 inch trance and it came across as a bike you would probably never need to replace as it ticks so many boxes.
Dont buy a CX bike if you want to ride on anything other than very smooth fireroads or grass tracks. As it will probably do you head in after a while, they simply arent anywhere near as good or capable as Mtb’s off road, and unless you spend alot of money arent really any lighter than an 27.5 hardtail either, and therefore not much quicker on road either.
An Anthem or Trance for off-road and a cheapish road bike like a Giant Defy, Spech Allez would make a great team. :-)
