It's always best to use multiple methods. The reason is simple. If one method fails, the other picks up the slack. If your skimmer pump dies, the scrubber saves you. If your scrubber pump dies, your skimmer saves you. They also compliment each other where one method might be a little better at removing something than the other and vice versa. The hair algae in my display all but disappeared after I added a scrubber.
That being said, the major problem with this hobby is burn out because of maintenance and constant care. I call it tank fatigue. You can't put your tank in the garage for a few weeks like your golf clubs or mountain bike when you need a break from it. Skimmers need to be cleaned. Scrubbers need to be scraped. Pellets need to be replaced and it never stops. You have to keep in mind what your willing give in time each week when you set up your equipment.
