I've been using HKS speed-loaders forever.  I chose them because they:
a)Came with the gun, so I didn't have to buy any.

b)Were always on sale or otherwise available at the time I needed a speed-loader.

c)The ones I already owned also fit new revolvers that I had bought, so it worked out.

d)They were the only ones available for specific guns (like 9mm for my S&W 547).

So since I haven't used other types in the past, like Safariland, etc., is there anything I'm missing out on?

Are other desings better, and if so why?

Good to get more information, always, Ross...but...if it ain't broke, don't fix it! <grin>

I like the Safariland COMP II speedloaders much better than the HKS.
They are spring loaded (faster), hold the rounds firmer than the HKS (no rattle) and have a much larger handle/release.
They worked fine for my GP100 in IDPA matches.
I plan on getting a set for my S&W 586 as well.

I was looking at some "one piece" speedloaders in the new Dillon catalog.  No buttons to press or anything like that.  Looked interesting enough to try for $9.95 a pair.

I like the Safariland and HKS the best. The Safariland is actually IMHO a better speedloader. But the reason I keep using HKS is because that is what I most familiar with, they are easy to find and nearly any speedloader case will work with them. The taller designs or other oddball types will give you fits sometimes when searching for gear to haul them in. So make sure you have a source of cases for whatever type you plan to get. Also, avoid the Max Fire (I think that's the name....has Max something in it...lol) as they are junk compared to HKS and Safariland.
