Like everything in aviation it depends. On the maintenance side the Johnson Bar may be a bit less expensive, but the gymnastics to put the gear up and down may make passengers nervous. My wife, sister-in-law, and mother definitely vocalized a preference for the electric gear. Since my wife is a voting member my current aircraft partnership her opinion on the little details is worth a little extra maintenance cost.
The knowledge of gear up verses down is the same is more or less the same with the only difference in the mechanism which moves the gear, your arm or an electric motor. On my F like the C, once the little green light is on and the red one is out the gear are equally likely to be down and locked be cause the squat switch changing the lights is the same. A gear could break off and you could still get a down and locked indication depending on exactly where the failure happened, but that is why we buy a slightly over engineered Mooney and not a soda can.
Both are an excellent choice for different reasons.
