I love 62g, but with worn in and lubed switches I think I could enjoy 55 to 60g even more. Personal taste, really. I don't like heavy switches and feel that lighter springs enhance the tactility more.
An interesting aside is that although I'm not a big fan of linear switches I find 62g to be my favourite variant (between Brown springs, 62g, Black springs and Clear springs). Also, I prefer linears WITHOUT orings / trampolines, but like to use them with tactile switches.
