I found force graphs helpful, but to a point. Actually feeling a switch yourself makes a big difference, especially when typing at ~100 words per minute. All the subtleties of a force curve will smooth out due to the quick strokes, and you just need to see how you like typing on each switch. I don't have a favorite switch--I like a number of different switches, and I'm currently typing this on stock vintage MX Blacks. I no longer favor Browns above all others, and I most definitely hate most rubber domes I come in contact with, but none of the Cherry switches I've tried so far have been "too heavy" at stock. I imagine I will find both types of Grays undeniably heavy, and probably won't like Greens too much, as I think Blues are as heavy as I want to go with a snap-bump. But that comes from experiencing lots of different switch variations. I would not have been able to say this without actually trying them out, and I'm a person who likes to read a lot of reviews before buying. In this instance, reviews only go so far.
P.S.: I should add: the purpose of your keyboard also makes a big difference. If you're going to type 8 hours a day, it's even more important to pick the right switch for You. If you're going to be using that keyboard for forum post typing, sending e-mails, and playing games at home--it doesn't matter as much and many switch types will do. I'd probably advocate linear switches for games if you like spamming your keys, but again, that's just my personal conclusion.
