Having a very similar dilemma myself after my Heckler was stolen.
Have tried zesty, spicy, 5, 5 AM, Alpine, new Heckler, Butcher, Transition Covert, Meta 6, Meta 5.5 but none of them have really excited me enough to make me want to buy them!
5 AM was probably my favourite going downhill but a bit too slack for normal riding.
Santacruz off the peg bikes just seem terrible … why does the heckler have a QR fork!
Going to look at a Pitch Pro tomorrow which seems quite a bargain. And Laggan demo day on Saturday so might attend that!
If you do like the Meta 5.5 Team you can get them reduced to £2k now.
Others on my list which I haven’t ridden:
Cube Stereo / Fritzz, Canyon Nerve AM, Mythic Spitfire, 5 Spot
Half tempted just to buy a wee hardtail for now as it’s starting to drive me crazy!
