Great examples Hammer. I loathe Kyle Busch the person but it is hard to deny his racing ability. The types of saves he makes are what you might expect from Drivers who cut their teeth on the early days of NASCAR, when dirt was common. Given that he was born after all of those guys had long retired, and after the King won his last race, and was probably too young to remember the last one Bobby Allison managed... he has a skill that is lacking in most of the rest of the modern Sprint Cup field.
It would be nice if they stopped equating Truck and NW wins to Cup though, by calling them all National series, as they weren't always all national series. The truck series is 20 years old this year (1995 first season). The Nationwide in its current recordkeeping dates back to 1982 (though its champions list goes back to the 50's even on official NASCAR sites), as they don't count all the touring late model sportsman events from 1981 and earlier. Think all of the Permatex 300 support races for the Daytona 500 as an example here. There are sites out there where researches share what results they have uncovered, trying to reconstruct an all-time wins list. As it is probably certain that someone has more wins than Kyle Busch when the entirety of the series history is included.
Consider it like NASCAR's demarcation of the "Modern Era" in Cup - defined as 1972 when the schedule was shortened. NASCAR kept Modern Era stats alongside total stats. Until Jeff Gordon passed him, Darrell Waltrip was the modern era wins leader, as his first win was in 1972 and thus all in the new era. So now that honor is Jeff Gordon's. A similar demarcation would be nice for the Nationwide/Busch/Busch Grand National/Budweiser Late Model Sportsman/Late Model Sportsman/etc. Leave the current 1982-current stats as that series' modern era.
Much of the life of the Busch series pre 2000 was the same rules as the Winston West series, i.e. they were the Grand national (a term that once was applied to early Winston cup). Busch North (today's K&N East series) was the same. At some point the Busch was elevated, and the Winston West series, once the equal of Cup cars, was no longer equal to Busch specs but now Busch North/K&N East. And unfortunately, with those changes, there were no changes in recordkeeping. The West series was still the west series, but long gone were the combo races of Winston Cup and Winston West. And gone were the combo races of Busch/Busch North. The only combo races recently has been the combo West/East race at Iowa Speedway.
