Personally, I'm not a fan of moonclips, at least for reloads.
I prefer Safariland Comp I speedloaders for their ease of operation. No need to twist a knob. Just insert the rounds into the chambers and push on the speedloader body. Some people have complained that they're not durable, but I can tell you I've dropped my loaders more times than I'd care to admit, including on concrete floors, and not only did they retain their rounds, they also functioned properly.
I've used Split-Six carriers, but don't like them. Those are the carriers that hold the loader on top of the belt with a snap cover over the top. I carry my reloads on my left side, and oftentimes the bolster of my car's seat would pop the snap when getting in and out of my car, causing my loader to fall off the belt. While I haven't had it happen to me, Split-Six carriers and Comp I speedloaders don't mix well because the loader's release mechanism rides on top of the belt; enough downward pressure can cause the loader to release all of its rounds.
My favorite speedloader pouch is the JOX. It's a kydex pouch that rides above the belt line, improving concealment. It's very secure, but releases the loader easily without having to undo any snaps. It has slots fore and aft for gripping the loader, which allows me to put grip tape on the speedloader body in such a way that it indexes the rounds for a proper reloading grip, as well as improving traction on the loader.
Having said all that, there's nothing wrong with strips. I've actually gone back to them for their lower profile. When I'm carrying my 642 as my only carry gun, I have a strip in a Simply Rugged belt pouch and often a second strip in a Side Guard Holsters pocket pouch. Nowadays I mostly carry my 642 as a BUG in an ankle holster, but I still carry a strip in the pocket pouch.
This is my opinion, based on my experience. YMMV.
