Which program is recommended SMR or SML

Which is better SMR or SML I am using SMR and get an error every time I exit to desktop. I tend to just close the box although sometimes I have bumped the Send report and close, I am sure Coffee Stain are tired of the errors I am sending them so which program is better and if its recommended SMR how do I stop those errors.

the SMR is this website, Use the mod manager. and CSS has a filter for these crashes and no you can’t remove them
