Yes, a Fluke is better in almost every way except price. It will be more rugged, have a real 600V/CatIII rating (and the $6 fuse which goes with it). But, unless you're using it on a day-in, day-out basis, it's probably overkill. A Fluke DC clamp meter is going to cost you $250+.
Other than the bottom-of-the-barrel $7 (sometimes free!) Harbor Freight ones, I haven't had any real issues with Chinese meters for non-critical use. Nothing like the bad luck you seem to have had with them.
I've got a Fluke 87 at home, but keep
one of these cheap DC clamp meters in the trailer. Works fine for simple automotive/RV stuff. A cheap meter kept in the camper is better than an expensive one left at home.
