There's no easy way to answer this question. You could get your first choice, be super happy with it, then get to a squadron full of jackasses and hate life. On the other hand, you could get one of your last choices (like me!) and wind up in a squadron with great people (for the most part) and come out of it with some stellar experiences.
The only recommendation I give students (and this is coming from an HSL guy) is to shoot for the newer platforms, particularly the 60R if you like the HSL/HSM mission.
A common misconception of HSM is that it's all CRUDES...there are and will be more carrier (CV) based squadrons in addition to the traditional expeditionary. If you're in one of those, you'll likely spend your time split between the carrier and the small boys, so you'll get to see the best (and worst) of both worlds. Most of those squadrons purposefully split time between the two for their H2Ps to give them the experience.
