Interesting poll; I've reloaded metallic cartridges for over forty years. I do disagree with your suggestion it's harder to reload for autoloaders. You do have to pick up your brass but that's not a big deal. You can even buy inexpensive devices to pick up the brass fairly easily without bending over. Since most of my shooting is on a concrete slab at my local club, I just use the push broom provided to corral them and then pick them up.
As to loading for revolvers being more versatile, I'm agree to a certain point. You do have certain power levels that must be maintained to operate an autoloader's action, but prudent use of bullet weight and propellant burn rate can get you a fairly wide range of power that works the action properly. Case in point the 10mm Auto. I own two: S&W 1006 and Gen2 Glock 20. For both I load down to 38 special velocities or up to max 10mm with 100% reliability. Just depends on what bullet and powder I choose and the weight of the recoil spring in certain cases. I always follow published data from known reputable sources.
There's a trade off for me: I find autos are a lot more fun but revolvers are simpler when it comes to brass recovery. But then, the last time I shot IDPA with a revolver, I still had to pick up a lot of brass that was scattered around. But for an old time scrounger, pickin' and grinnin' was always just part of the process. And considering the cost of even once-fired brass now days, the pickin' part always means a lot of the grinnin' part ... at least on the inside.
