Welcome to Geekhack!
Any reasonable mechanical keyboard will be a big step up from the rubber dome keyboard you are probably using now. I started with MX blues too, although I was trying to replicate the feel of some old NEC blue oval switches, and MX blues were the closest match.
Since then I've settled on 45g Topre (as in HHKB) and buckling spring as my two favourite switches, closely followed by MX clears, although I'm typing this on MX greens.
You may be in for a long and interesting ride trying different keyboards
