Is the 'best meditation you do' the meditation you do?

There is a pithy saying for keeping fit that goes > The 'best exercise you do' is the exercise you do i.e. the most important thing is to find something you enjoy and you can stick with rather that do the scientifically proven 'more effective exercise' that you maybe don't enjoy as much. So I was wondering is the same true of meditation i.e. > The 'best meditation you do' the meditation you do So to fill it out - is it more important to find the meditation that suits you personally and perhaps adapt and tweak it until it really suits or is it better to pick a tradition and follow their methods to the letter and force your way through it?
