To the OP, it's quite an open-ended question and so with no context in which to provide an answer, it's a pot shot
But I recently purchased a Tikka T3 Lite chambered in .223 and am really enjoying it. Semi-autos (whether AR style or less tactical shapes) fill the need as an excellent defensive firearm, a great design for hunting in high-pressure situations (e.g. hogs perhaps). And I have quite a few of them. But they also tend to push me to shoot more quickly and more rounds than I otherwise need to.
The bolt action design brings me back to summer camp when I was a kid of age in single digits, shooting five rounds and then walking out to check my work, then being granted another five rounds by the 'range officer'.
Today, the Tikka bolt brings me back to those times, provides a very accurate and easily carried platform, shoots (relatively) low-cost ammo while still being practical for certain hunting needs - though I am not a hunter.
Best of all it motivates me to savor each shot, practicing my breathing, my sighting and my trigger work. Popping off one round and then a pause to regroup my thoughts. Very zen perhaps but it works for me.
I'm not sure this is the last gun I would hold on to if all but one had to go, but for sheer shooting pleasure it absolutely is.
