Hilleberg Nallo 2 expensive but very good, quick to erect, light weight and very sturdy.
If money's genuinely not an issue, get a hilleberg. I've their larger model kaitum 2 gt ( two porches, one very large) and it's outstanding. It was however fearsomely expensive. The nallo 2 is significantly lighter, with only one (normal size) porch - which i've also now bought for a lightweight long distance walking trip but not yet used. There's also nallo gt with a larger porch, and the kaitum 2 (non gt) with two normal porches which are in-between models. The attention to detail on these tents is really superb - little things like plastic cups at far end of where you stuff the poles, so you can put it up easily from one side; poles colour coded so you know which ne goes where, good thought to ventilation; it all goes up at once - inner outer, the lot, can get by with nly 4 pegs, stands rough weather, very light for the size / very big for the weight - but seriously expensive t can't be denied.
Middling price - i've previously stayed in a vaude, and though seemed flimsy it stood up to some evil mountain weather, was light, and very easy to put up. Good gear for sensible money
Been a bit disapointed ny terra nova, as though seeimnlgy very strong, was much more of a faff to put up, and developed a leaky groundsheet.
Tent snoberry aside, there are some incredibly cheap tents which are essentially knock offs of pukka makes which would probably be fine for cycle camping if questionable for mountaineering.
