Transcript quantification using the reference transcriptome(gencode) and the raw RNA-Seq reads without mapping it to reference genome.

I am just curious to know how accurate would be the transcript quantification of the RNA-Seq reads using tools like Sailfish/Salmon without using the mapping tool like HISAT or STAR. Basically, I want to skip the mapping/aligning of the reads to it's reference genome and focus on isoform abundance study. Is this a good approach for transcript abundance study in eukaryotes?

if the gene models are correct and you want only to quantify known genes, it is perfectly fine.

Thank you for your suggestions JC.
