Natureboy,
When Lehigh Valley lube went off the market, and my horded supply was used up, I tried Shenandoah Valley and my experience with it is that has a tendency to form large white flakes in the bottom of the bottle, which Lehigh Valley never did. That tells me that the formula is not the same. Though SV is a good lube, IMHO it doesn't measure up to Lehigh Valley.
When George Sutton came out with Mr. Flintlock's Lube he posted here on the ALR forum that it is the old Lehigh Valley Lube under a different name. IIRC, that is due to trademark restrictions on the name Lehigh Valley Lube. George can jump in and correct me it that's wrong. After the good feed back on it, I ordered a case for a few fellow shooters and myself to try out and use as prizes in shoots. The response has been all very positive from all who have tried it around here. I'm going to contact George and order another case in a few days.
I've never tried Hoppe's lube, but I hear it's pretty good. However, a couple of the shooters here that used it and tried Mr. Flintlock's Lube switched to Mr. Flintlock's Lube. But, as you said, there are lots of different preferences for patch lube of every description. Some use exotic homemade formulas, some simple homemade formulas, some commercial formulas, and some use plain old spit.
Whatever works best for you is what you should use. I'll stick to Mr. Flintlock's Lube because it is Lehigh Valley Lube which I always used and loved.
