This was my original agony when choosing my first 'real' rifle.
I WASTED TWO YEARS TIME TRYING TO WEIGH IT OUT.
The long story short:
I went into a BIG 5 Sporting Goods store one day and saw a Remington 700 BDL in 7mm Rem.Mag. on the wall and bought it.
It is to this day my favorite rifle.
Yes, it's a 'push-feed Remington with a brazed on handle in a synthetic stock and a small-bore magnum'...SO WHAT?!
It's accurate; doesn't kick much harder (actually, I like it better than a .30-06); doesn't jam; takes one round at a time easily; the Police and Military use the same action; etc.
I really pissed off all the guys who told me to "get a Winchester Model 70 in .30-06".
My original choice was going to be a Savage 'Tactical' in .308 with a Weaver scope/rings/base setup like I saw in a Guns&Weapons for Law Enforcement article.
I should've just gotten THAT one and started shooting!
But, NO! I had to garner the wisdom of all the experts!
NONE of the EXPERTS would encourage me to go get the Savage and start shooting. ALL of the EXPERTS wanted me to get THEIR choice...it was the only one, you know?
To answer your original question, though?
I'd take a Remington 700 BDL in .300 Win.Mag. for only ONE rifle.
Probably the Police version, or the Sendero.
Bottom Line:
Don't wait 2 years! Get what YOU want and START SHOOTING!
Good Luck!
