This really has nothing to do with how you play it or how it sounds, and only with how you read and write the musical notation.
When you write any form of syncopation, you want to notate it so that the beats are still apparent.
Here's an example with a very common syncopation known in Latin music as a 'tresillo',
The following rhythm is the exact same rhythm, just in a different notation.
The only difference is that in the second version, the 4/4 meter is more visible.
If I add a quarter note beat alongside both, you can tell.
In the first version, the 2nd and 3rd beats are obscured within the dotted notes. In the second version the notes of the syncopated rhythm visibly line up with the 4/4 beat and therefore the meter is better emphasized. It uses the beamed 8th notes to show that there is a note halfway between the 2nd and 3rd beats and ties to link up the long notes.
The first version is fine if you want to emphasize the 3 + 3 + 2 (or 1.5 + 1.5 + 1) rhythm as the beat, especially if the music is based on that tresillo structure. However, the second version is better notation if the 4/4 beat is more important, like when the other notes or instruments in the piece are structured around the beat and not the tresillo pattern.
As a general notational rule, use beams and dots to group up notes within a metric beat, and ties to link up notes that play across more than one beat or between beats.
