The closest you'll get to a laptop chiclet board in a mech is cherry ML, which are also pretty cheap and easy to find on Ebay
ML's only really come into their own with lubing. Stock they feel nice if you hit them dead centre, but the closer key spacing and binding when hitting them off centre ruins the experience for me. Lubed they're awesome, but it's very hard to open up the switches when they're on the PCB, so it's quite a hassle to lube a whole board.
Easiest transition may well be a Realforce uniform (45 or 55g, depending on preferences) board, but it's an expensive way to jump into mechs and the combination of price AND longer key travel may be a bit much.
For an MX board, I would go with Clears with orings and Cherry profile keycaps. The Clears have the most similar tactility to scissor switches and the orings help with bottom out feel and a slight travel reduction, especially with Cherry profile caps as they have such a small clearance to the switch case when pressed. MX are nice if you like to customise your board, since there are so many boards and so many keycaps available for them, that's a big reason why I use MX switches. Not to mention how moddable the switches themselves are (trampoline mod, springs, latex mod, stickers, lube, etc) and they support LED backlighting.
P.S. - In the future, there
will be a board available with Krytox lubed ML switches, doubleshot keycaps and better key spacing...
still got some development work to be done, but I'll try to get the first boards out before the end of the year
