At any speed greater than a walk you will not notice the "effort" required to turn the wheel.
They say there are no such thing as a stupid question. They say there is always the exception that proves the rule. Don't be the exception.

Here's the easy answer - the faster ratio box will require 20% more torque turning the steering wheel.
What affects ease of steering? Wide tires Worn tires, because tread blocks are shorter and stiffer Non-stock wheels, because they put the center of the contact patch farther away from the imaginary line going through each ball joint. This distance is a lever arm.
Until recently I drove my '64Dog daily. It had 31-10.50/15 tires on the front and a 7" wheel replacing the 16 x 5" stock rims. It was a bear to turn the steering wheel before it started rolling.
Your new setup should work fine and will be a little easier to drive on Interstates. No steering box allows a dead spot in the center of travel. One time I tracked down the sloppiness to a worn out system to the idler arm. Turn the steering wheel and the arm moved up and down.

R. Good point - Even though all new parts were used during the rebuild - does not mean that something other than the box could have loosened up in the few thousand miles since then. Will definitely need to verify before replacing the box.

I honestly dont understand why anyone would ever think a faster ratio is "too much". You cant have too much ov a good thing. Its not 10:1. 16:1 is a nice compromise. As for steering effort, even if it IS a bit hard, you get used to it. Before i started training, i had two mechanic friends, racers, both bodybuilders, both bigger and stronger than me. I had a manual box in my Charger with 295's up front and a tiny aftermarket steering wheel. Neither could move my car, without serious effort. Drove almost like power steering for me. You get used to it. Its not going to be 'twitchy' at speed (new cars can be well faster... no one complains there, its just more ov a good thing). At your size? No problem.
Get the 16:1 box. I'm going 12.7:1 on mine, and again... 295's up front, and a tiny wheel.

Quick ratio box, 15" radial tires equals alot of muscle when parking major effort to turn the wheel.. Once moving all is fine... Note that we have a 16 to 1 manual box and 15" radials on my 70RR. One does get use to it, but it does seem like a big step when changing over from the daily driver Dakota that has power steering. Just my $0.02...

Find you slop first. Look at the tubes for LCa in k bar. Welds could be broken. Found that a few times. Can't recall if that caused slop or instability.
If Oem look isn't a must, look into that bottom bearing kit somebody was selling for below pitman. I tend to think you'll find the issue someplace along the way.
Can't answer about the ratio.
I want my fair share

I have a 16:1 box in my challenger. It's comparable to a power steering box with no belt when it comes to slow speed turns, however it changes lanes with the flick of the wrist. I would not hesitate to use a 20:1 box, in fact, I probably would prefer it for parking. I'm 6', 175lb. So if it's no sweat for me, should be no sweat for you!
1973 challenger Dana. 4 speed. Low deck.

I have a 20:1 in a 69 runner with 215/70-15 tires up front and yes it's a tad heavy below walking speed, but other wise it's a good ratio. Drives nice. Get it.
I too am going to deal with firm feel shortly as we think my mopar performance worm is giving me some grief...... Just have to take my box out and send it to them so they can use it. Saves mailing a core in after the fact too.
20:1 is just a hair over 4 turns lock to lock. Stock 24:1 is supposedly 5 7/8 turns lock to lock which can be a bit 'handy' for cruising.
