It really doesn't matter. I generally don't start the engine because I don't want all that heat and fumes around while I working. They bleed just fine either way.
Leave engine off. Start bleeding with the closest to the master cylinder wheel first. Order: Drivers front, passinger front, drivers rear, and last passinger rear.

I have read on here that the order is reverse of that. So which one is it? Is it just a matter of preference?

LOL That is how it got stripped in the first place. You know this redneck reached for the vice-grips at first sign of strippage!!
Be VERY careful with the vice grips on the warbled bleeder valve. I would put penetrating oil on it several times over a 24 hour period. If it breaks, you're screwed and will have to do the easy out thing or replace the part.
On the order, I have always done farthest away first and a glass jar.

You want to bleed the fartherest wheel cyl from the MC first, then next closest, etc. If you start with the closest first, the air in the fartherest will start moving to the MC so you will have to bleed more brake fluid when you get to the fartherest to get the air that has moved farther down the line back to the WC.
That makes sense. But either which way the air gets bleed out. Yes, it might move back towards the MC but it won't move down the already bleed lines. No matter if you end up bleeding farthest to nearest or the other way the fluid and the air gets pushed from the MC to the WC you are bleeding.
Both ways are correct, just don't let the air re-enter the bleed zerk after bleeding.
The best way to fix a stripped bleed valve is to replace the wheel cylinder. They are under $10 each at Autozone and you are going to bleed the system anyway. This is much easier, IMO, than fighting that thing under the truck with a pair of vise-grips.
