It's more than just "matching" what the original cabinet had.
Leaf switches have advantanges, So do microswitches.
Here's a quick run down. You need to decide what you want for your particular preferences, regardless of the game being played/etc..:
Leaf:
+ Relatively quiet. Only quiet tap of leaves meeting, more noise in plunger/spring usually themselves.
+ Smooth movement into and through point of contact (e.g. like a good golf swing!

)
+ What you "grew up with" if you're into Pre-1986 type games.
+ (or -) Special lengths for wood vs metal control panels.. pick the right type to use otherwise you'll be routing or building up.
- Needs to be cleaned/polished periodically which can affect "contact"
- Bends from use/heavy use.. Doesn't stay in same position. You must press harder, or push joystick more in that direction to receive "contact". Hard to realign "exactly" without buying new switch.
- More expensive ($4 + per button + holder + leaf)
- More parts (Housing, Plunger, Spring, nut, Holder, Leaf assembly (and if old style, multiple little parts in the leaf assembly instead of molded into plastic, but allowed for better repairs)
Microswitch:
- Noiser than leaf. Hear (and feel) it "grab" when it clicks the switch (feel point of contact in some cases). Cabinet/panel top can mask some of the sound, but not all of it
- Pretty much stops at point of contact ("click"), no smooth follow through if you like that.
- Never translucent.. can't "ideally" light from behind like leaf switches. However many people are now mounting colored or white, high brightness LED's in the center of the switch under the plunger to get a glowing effect. Not the same as translucent, but a nice "neon" effect if you're into lighted panels.
- Typically only 1 length (long) though some short ones have been used.
+ Consistent, identical points of contact (within a SMALL range anyway).
+ No chance of bending/breaking due to use/heavy use (save for a mallet pressed against a button, of course, but the button will break before the switch typically, or switch just pop out of the button holder)
+ Cheaper (Nylon button housing, plunger, spring, nut and micro switch..usually 90 cents to $1.50 in quantity.)
+ Less parts, easily swapable for repair/replacement if you ever need to
