All depends on how much time you have. I was there a few months back and flew in SQ and on the way back was feeling lazy and wanted to get home asap so changed over to MH rather then go via SQ.

Its only a 5hr flight I guess so just depends how eager you are to fly a better product. On the way out I had plenty time so flew SQ First and way back flew MH J. Lots of difference in in Biz but I was home by 9pm.
