IMAO, no, not since they changed the ramming rules.

The warheads are just too expensive to be cost-effective, except in rare circumstances.

Ramming does have some advantages. If your enemy has such huge ECM superiority that you can't hit him with direct-fire weps, and such heavy PD that you can't get him with fighters or seekers, then ramming may be your Last resort.
