It's tuned an octave lower than a regular 6-string guitar from the factory. So it wouldn't be a great fit for strumming as it would sound muddy. However, flat picking and finger picking is probably its mainstay. Particularly if you are concerned with fitting into the mix in a band with bass and regular guitar players.
Some tune it higher, like a fourth below standard tuning so strumming can sound better. I'd guess that it would require different strings. In that case a gauge in-between what the factory ships and common gauges found on a regular guitar.
Unless you like the novelty of that guitar, you probably would be better off with a regular guitar and a pedal to get that lower octave. If you already have regular guitars and want to add this, I'd say go for it. It's not that expensive.
