I don't fly the NG, but in general it's always good to stick to SOPs as much as possible.
In other words, if you must go missed at 1500', then yes, select TOGA and fly the machine the way it was designed to be flown.
I once watched a missed go a little wacky after LOC/GS capture and the airport changed the landing runway. The pilot was reluctant to select TOGA as he was instructed to maintain an altitude just 500' above.
Basically every situation is different and that's where experience, good judgement and systems knowledge really pay off.
Happy New Year.
