There are a number of ways to measure which Myachi would be the "best". For a beginner, the most important thing it how quickly a Myachi breaks in and how easy it is to catch right away. For these players, a corduroy sack such as the Shockwave, the Boss Tweed, the Starting Line or the Braveheart would be the best.
For an experienced player, the break in time is not as much of a factor and thus the only real concern is how well the sack jams once it is completely broken in. Again, this is open to opinion, but the three Myachis most often mentioned as the "best" by veteran Myachi players are the Calvin, the Coreyster and the Black Belt.
Myachi Masters travel all over the country and have been in Utah a few times in the last few years, mostly in and around the Logan area. Incidentally, the worlds best Myachi player is a Utah native, known as Maverick in the world of Myachi.

Technically, there is no "least rare" Myachi, since all Myachis that are currently available on myachi.com have the same level of commonness, however, the most plentiful Myachi is the Sobe '02, of which 100,000 were made. Since this was last manufactured in 2002 it has since become relatively rare despite this high number. The Black Butter is also often referred to as the "Most Common" Myachi, since it was made in greater numbers than any other series (non-promotional) sack. Again, since it was last released in 2008, it should no longer be considered the "Least Rare" either. The best answer to your question is that any sack offered in the 4.5 series is currently the "Least Rare".
There are over 500 different types of Myachi on the market and the majority of those types are out of production and therefore rare. A few things you can do to check and see if a Myachi is rare include:Look for the series # on the tag. The lower the number, the rarer the Myachi. Anything from 4.1 up are currently considered common.If there is no series # on the tag, the myachi is either a promotional, which means it is almost certainly rare, or it came from a series before the number was added to the tag (series 2.2 or before) and is rare.If the tag is one ply and printed rather than a woven fabric tag, it is an extremely rare Myachi.If the Myachi has a keychain loop sticking out of the side of it, it is likely very rare.
