Good 6-point socket and breaker bar, and apply force in small impacts instead of slowly ramping up: This makes metal creep more unlikely, so you won't round-off the nut.
A good ring spanner would be my 2nd choice. And an open end spanner my 3rd. I'd never use an adjustable for this.
If you need to hold the bolt while undoing the nut, I'd use a ring spanner on the bolt, and socket+breaker bar on the nut.
Never buy cheap tools, and -when possible- work on the nut and not the bolt.
Also, for assembly:
If you use a torque-wrench to tighten up, remember that torque is specified for clean and dry threads. If you have used WD40 or other lubricants, low friction can make you overtighten the bolt with the spec torque.
