So what's the difference in your opinion?
Good Socratic technique. I'll pick up the ball and run with it. No big deal on flat and level, but on inclines: Car has parking brake and, if auto trans, parking pawl in P(ark) position; also can turn wheels to curb. Bike has none of those three, but can put in gear like manual trans car. Sure, bike has jiffy stand, and if it's on the peg, there's some measure of safety/stability...and no one
ever had incomplete engagement of stand, or HD equipment failure, or kids playing on bike when you're not there, or earthquakes.

I rather not risk my expensive paint job, tins, levers, grips, etc. by relying on just one method. So yes, I park in gear anytime I'm not in the garage.
To the original discussion, however, I start in neutral, with clutch in, unless I stall in traffic or am in an unstable position where safety considerations override the benefits of less stress on starter and battery...and I always engage a brake when hitting the starter.
