To be fair, the collie shouldn't really be compared to the BC to judge working ability. Instead, if I were working on reviving working ability in the collie, I'd look to the English Shepherd as a guide. Collies were refined into their show version before their working cousins began to be bred strongly for trial success.
So it's not as if the collie fell away from the BC's trial standard of work - the dogs that were picked for the show dog material were general purpose shepherd's dogs, mostly the yard dogs that the highbrow fanciers saw most with the Scottish sheep handlers.
Bearded collies are actually closer to BCs, genetically, having split off rather later (and with some Beardies still popping up in the BC gene pool). The few lines of working Beardies that are left, work with eye and have natural outruns like their BC cousins, though not quite as refined.
Collies are plain workers, more task oriented than pressure sensitive. Eye and pressure sensitivity (they are related) is the first thing to go when one abandons breeding for stock work, and it's the hardest to get back without outcrossing or inbreeding to unsafe ratios. Eye is required to work stock in very large areas, such as commercial breeders of thousands of head graze in. Not too much eye, but enough that the dogs can save steps over the miles they cover on big gathers - otherwise dogs that have to control stock with movement rather than eyeballing them, end up exhausted before the first hundred or so head are taken up.
New Zealand sheep management is an interesting example of how selecting for one physical trait other than work, can affect your gene pool and limit its working ability.
Border Collies in the UK work great steep hills, plains, stockyards, chutes, drive sheep to market, and work all kinds of stock. They do here in the US as well, and in fact have proven their effectiveness in an even wider range of working environments: desert, heavy brush, dense woods, tidal islands, herding goats, wild cattle, feral sheep, fallow elk and deer, swine, buffalo, and many other types of stock the original developers of the breed never dreamed of.
In New Zealand and Australia, sheep ranchers prefer smooth coats in their dogs. It's a highly practical choice, particularly in Australia, where the long coat can hide all kinds of horrible parasites and critters and potentially deadly foliage bits.
Smooth coat is dominant, meaning one has to keep culling the gene pool each generation as the recessive long coats will pop up over and over.
Starting from the same genetics as today's BCs, ranchers over there have basically three choices of dogs to work with: smooth coated lines of dogs that either head, or drive, or work yards; or Border Collies that can do any of them, but will throw rough coats.
What is generally done, in fact, is to have teams of dogs from all these groups - this works just fine (and the dogs are very cool - I'd love to have a NZ Heading Dog someday). NZ Headers work their way, and are supremely useful. The Huntaway is really unique and a dog I'd like to see more of over here. I have friends with Kelpies and I love their style. All these are great examples of dogs that have different working standards from the BC, and breeders have made sure that they breed true to these standards.
