I'm personally changing my approach to the latter, as on live realms it's simply impossible to get truly skill based competition - and I'm not only talking about counter compositions that are present for every setup you may imagine, but also the fact you might not be so lucky to find best players playing the best synergy possible for your setup. I think TR is better place for competitive play and it saves you all drama about "I've worked 6 months on this char and for what??".

But then as I've said, it all depends on ones goal.
