LOL!
To the OP, hint: it is "Brake", not "Break".
For wheel removal, discs are really no more complex than rim brakes - you just need to ensure that the disc slides into the caliper as you move the axle towards the dropout.
Maintenance wise, mechanical (cable actuated) discs are the simplest to work on, and hydraulic brakes are more complex *if* you ever need to do work beyond brake pad replacement.
