The M1A definitely seems like the best "do anything" rifle.
But I am intrigued (or put off by the price), that for the price of one gun I could have two, suppose if I continue that logic though I could have 3,4,5 for the same money with increasingly cheaper guns.
The price kept me from getting one for a long time, but I'll say with no hesitations that I don't regret a penny of it. And this is from someone who does not make many gun purchases, because of a tight budget.
