It can be done with either process, however, for the laser process, the
relatively close proximity of the holes will require some careful
programming to counteract the accumulation of heat.

Abrasive WaterJet (AWJ) would be my choice because there is no heat
involved with the process.

If you don't have a local waterjet house I can recommend:
