How to choose the best imputation table?

Hi dear developer, 

I used your pipeline to perform the imputation of my non-target metabolomics data. 

My question is: among the four output tables  (after_trKNN_imp_table, after_HM_imp_table, after_QRILC_imp_table, after_GS_imp_table) of your pipeline, how to choose the best imputation?  Do you have a rule and metric for the choice of the best table ?
