Same tricks can be pulled with Advanced Sensors too, if you need options. Though they're slightly more pricey than pattern analyzers.

The difference between these and BB-8 is fewer actions overall, but you have more freedom in which action you use to get things started (starting with a barrel roll isn't always optimal). Though this can be combined with BB-8 with some utility.
