I think whether you use a memo payee is purely a matter of style. A valid argument could be made for either way. Your way is fine, and if it works for you by all means continue to use it.I use a memo payee for all security transactions other than income. For example, General Motors/Purchase, IBM/Sale, Hulett Packard/Stock Split would all be memo payees. PG&E/Dividends would be a regular payee.
My rationale is that the income transactions are recurring in nature, while the asset transactions are usually one-time in nature (and there may be dozens of these transactions every year). Why add dozens of payees to your list if you're only going to use each of them once? Larger payee lists are slower to load and are generally quite cumbersome.
Specifically in the case of a stock spin off, you need to use the payee twice (once to record the "sale", reducing the 1st company's basis, and again to record the "purchase" of the new company's shares). If you recorded the first transaction with a regular payee (i.e. not a memo) then the second transaction would be very confusing. FN would remember the 1st transaction
as a "sale" so the system would try to enter the second transaction as a "sale" (deposit) as well when you really need it to be a "purchase" (charge).
Of course I realize you can work around this in several different ways but that would be very confusing to many users. Suggesting that the user make this a memo payee alleviated that confusion.
Note that the names of memo payees show up on all reports except the "summary by payee." I use the Transactions by Account report (for the asset account in question) in the situation you describe, and I believe it provides all the necessary information.
