store_result uses all same functions as fetch_result. It call 
db_mysql_convert_result() then many functions called by 
db_mysql_convert_result().

fetch_result more smart and do many works internally.

so if store_result and fetch_result haven't other differences we can 
increase performance because fetch_result don't make unnecessary 
functions calls. IMHO
