I'd think the rough basic answer is, "No." There isn't one maker/FMJ that is best for all purposes.
Smoothing the answer up is that FMJ is probably a good choice for general use, practice, etc. A typical FMJ round from a good manufacturer should be consistent, feed well, be reliable, reasonably accurate, etc., and might well be the least expensive option. Some shooters may find reloading a good idea, especially high volume shooters. Re-using brass may drive the price down and while lead bullets might be cheaper, I'm not sure that's always the case and environmental concerns or range requirements may vary. Steel or aluminum cases may be cheaper for practice and less trouble to retrieve and reuse (you can't really, but maybe scoop up for scrap/recycling in some ways?). Price and availablity may vary but I'd think that may result in different makers moving to the top of the list at times. Recently I found bulk Winchester white box .40 S&W FMJ at WalMart in 50 and 200 round boxes and the 200 round sale price was crazy cheap. Cheaper than available on-line, etc. Just found a 250 round box of Ranger Brass .40 locally that was extremely competitive with on line pricing. Both worked fine but the Winchester was still cheaper and after comparing in use, if I find the Winchester again at that price, I'll get more. I would not be uncomfortable buying other makers, S&B, Remington, etc. For FMJ/practice, I'd go with what was cheapest.
Others may find reloads or remanufactured ammo for less, maybe steel or aluminum case ammo. Local sources/pricing may or may not be competitive but the hassles of shipping and freight costs may make different brands or sources better at times. Market forces will drive price and availability changes rapidly these days, too. There may or may not be warranty/quality issue with some types as well.
I would not use FMJ for personal protection if I could avoid it. While real world, especially military, experience shows FMJ type ammunition "works," real world experiences also show that it is less effective than readily available (for most of us) alternatives. There are a lot of factors that differ between military use, legal considerations of various sorts, and tons of discussions on these issues out there. What I do is to some extent look for reliable brands, standardized or comparable test results of that load if available, and availability such that I can test fire a reasonable quantity of that specific load in the gun I expect to use it in to test reliability.
