I don't have a 55g board so I can't speak for that but having gotten 2 45g uniform boards I can tell you that 45 feels a tad heavier than 62g clears. It took me about a day to grow on, and now I really like it. The tactility is more noticeable and less rough than clears and it's really great to type on. I'd be hesitant to go for 55g without trying it because of how 45g feels, however. The best way to be sure is to try it for yourself, unfortunately that's just not a thing you can do a lot of the time.
