This has nothing to do with PD or not. Missiles are useless from the very start of the game, until the very end. It's not the dmg, it's that they are mechanically broken.
It's never worth it to "rush" science like that. I mean, it's a different way to play if you want to try something new, but if you are talking about efficiency, simply colony spamming is the way to go. The additional energy/minerals -> bigger fleet is just so much stronger than any advantage you could ever get from science. Not to mention the fact that you will very quickly get the best ship techs anyway, from salvaging debris. In fact, I would do the opposite, always choosing techs that increase your resource output, and only researching ship techs if you don't have any other options.
Compared to many other 4x games, science in Stellaris, is very weak. It's simply not possible to win games by having a technologically superior fleet, since said fleet can easily be countered by higher numbers (which are limited by minerals/energy), and there is no "science victory". Minerals and energy on the other hand, is king, and will win you the game every time.
