[General] "All other things being equal....."

[infiniteone]

There are two examples below.

A: The phone's camera is very important to you.All other things being equal, you'll buy the phone with the best camera.

B :The phone's camera is very important to you. All the other things being equal, you'll buy the phone with the best camera.

I think B is proper. With the phone removed from consideration, things to consider is "the rest" except the phone. But, It seems that native speakers use both and the "A"-type expression seems to used more often.
As a non-native speaker, I am so confused which to use.
I need help.

A. is idiomatic. You don't say "the".
You could use "the" if you have a list of specific other things in mind (such as the functions of a phone), but generally when you use this expression, you don't. I can't recall a native using "the".
E.g: "University A has a better teaching staff than University B. All other things being equal, I'd go to University A."
The point is, you don't have a list of "all the other things" because, by definition, everything but the teaching staff is included.

It's a little confusing but I see what you mean. But then, English itself is not that logical as the logic would dictate. All you have to do is loosen up a little. Personally, other things being equal is the most familiar expression.
