Learn English – “Take account of” vs. “take into account”

Yes, it's a matter of style. One means that you account for something in your decision/judgment; the other means that you consider it during your decision/judgment. It comes to the same thing.

In this context, bearings means

the direction or position of something, or the direction of movement, relative to a fixed point. It is usually measured in degrees, typically with magnetic north as zero:

the Point is on a bearing of 015°

there were no steeples or bridges from which to take a bearing

(one's bearings) awareness of one’s position relative to one’s surroundings:

he flashed the torch around, trying to get his bearings

While there is no rigid distinction between these phrases, the connotation seems to be as follows:

find one's bearings - to settle into a direction or path (literally or figuratively), usually after being disoriented

get one's bearings - again to settle into a direction, but with less suggestion of previously being lost or disoriented

take one's bearings - to be in the process of gauging orientation or direction, also with little suggestion of disorientation; you would take your bearings before finding your bearings or getting your bearings

The distinctions are subtle at best, and the terms may often be used interchangeably with little confusion, especially the first two. Get seems to be the most common form.
