Probably my little 308 Ruger scout. while it's very agricultural, does nothing exceptionally well, it just works and proven to be life proof.
And I don't stress about dings, treated rough and keeps coming back for more. And 308 covers pretty well everything that draws breath
I still laugh about a trip up the Cape when one of the blokes joked about it being cute lol
And on that particular trip the 'cute' rig despatched more oinkers stalking, out of the vehicles and from chopper than the rest of them combined
