Typically I dislike Merit/Flaw systems but there are games where I don't mind them, e.g. in Ars Magica. It also has the provision that flaws must be meaningful, i.e. they only allow you to pick a merit if they are likely to come up in actual play. Otherwise you're free to pick flaws but you won't get any benefits for it.
I generally prefer 'paired traits', i.e. traits that grant you an advantage in some situations but are detrimental in others. This makes it a lot easier on the game designers to properly balance them.
Being allowed to pick them freely usually just turns them into yet another min/max tool.
