I like having large pulse lasers on my clipper, they can take down shields pretty well and do a pretty good amount of module damage. I do want to try out burst lasers because i see them as being a midway point between pulse and beam.However, when I did use beam lasers I had two C3 beams, and the problem i kept running into was that they would overheat my ship, and they couldn't fire for extended periods. On the plus side they can destroy shields and small ships easily, they cant really be used effectively for destroying modules compared to pulse or burst though.
