This depends on skill level & musical context.
If one is easier for you to do, then do that one for now. It might be easier because of the shape or the fretboard position. It might be easier to use in order to get from the chord before it, and, or to the chord after it.
The chords have slightly different voicings & timbres. Both are B-flat major chords but there are many different ways to play any given chord on the guitar. Some are played lower on the fretboard, some higher, some with different sets of strings. All these factors result in slightly different variations on the same chord. One might be more appropriate than another in a certain song or musical context.

Find the B-flat note on the A string, 1st fret. Play an A shaped baree chord.

You can leave off the top note of that chord if it's too difficult for now. It's still a B-flat chord because it has all notes you need.

|--3--(D)--------|
|--3--(Bb)-------|
|--3--(F)---------|

In fact you could just play the middle 3 strings.

That's all you need for a B-flat chord because it has the 3 notes necessary to form the chord. But you might want to add the low B-flat to flesh out the sound. Especially if the other chords you are using have lower bass notes.
[quote=mindexmaster]Do I just try to memorise which barre chord shape to use for each chord or is there some kind of method I just don't know?
Yes, learn as many as you can. Ultimately you want as many options as possible at your fingertips in order to make your playing more musical.
For now start with both the E & A shaped barre chords. Learn the musical alphabet on both strings & practice playing both kinds of barre chords on every fret & what chord that is. Do it for all major & minor chords.
I cover that in this tutorial.

And then show how to systemically practice it in this tutorial.

Hope that helps!
