You should raise if you have a playable hand, because of the increased chances of picking up the blinds and because you are relatively unlikely to get a playable hand in the following hand where time will be collected if you win this hand uncontested. This way, you increase your chances of winning the blinds while very likely not having to sacrifice anything on the next hand. Granted, this depends on table texture, your position, etc, but if you are likely to steal the blinds you might as well. You will unlikely regain the equity you lose by giving up your chance to steal the blinds by open-limping and allowing others into the pot.
