Hi!
I have a switch tester with red, black, gray, white, blue, green, clear, brown, and dark gray(?). Of those, I think I might like black and clear the most; pretty sure I wouldn't like browns. I wanted to try greens for a while, but I can't stand the high pitched sound of blues and greens anymore. I bought some 67g Zealios to put in the RAMA M65-A when that comes in. At the moment, my favorite switches are buckling spring and Matias Click.
I'm currently in the M65-A GB, the Ellipse new model F GB, and the SA 1965 GB (mainly because I wanted to try SA). I got a lot of extras for the F77 though, like first aid kit, both case sizes, extra key caps, so that was pretty expensive (somewhere around $600 if IIRC).
