The other advantage of soft limits is that mach3 won't let you jog into the limits and slows the machine to a nice controlled stop. It also checks your G-code and if you are going to pass the soft limits warns you.

Home switches are priceless and if you are going to the trouble of fitting limits you'd be silly not use them as home switches as well.

Just to add to Jazz's comment, and possibly to head off the next question, apart from position (limit switches on the extremes of travel, home switches at some arbitrary position within the extremes of travel - possible a limit switch) - the distinction is made within the Mach3 settings - you'll bind an input (Pin 11/12/13 - assume X/Y/Z, according to the silk-screen printing on the board) to a function (limit/home) within the Mach3 inputs, then Mach3 takes over from there.
