If you refer to the rules of stability of resonance structures u will find that the structure which has most number of atoms having complete octets are the most stable. here 

R-CΞO+  

has a complete octet for all the atoms including C which is not true for te other structure.

IN R-C=-O+ ALL ATOMS HAVE OCTET CONFIGURATION AND IN R-C+=O CARBON HAS SIX ELECTRONS AND NOT IN ITS OCTET THUS THE FORMER CANNONICAL STRUCTURE OF ACYLIUM ION IS MUCH MORE STABLE THAN THE LATTER
