Only 2nd hand info, never heard of a GE 45 but the other brands you name are reputeed to be fine; i have them in collection for a coming amp project and my buddies report brand does not make a big differnece, all brands are fine provided the circuit is ok.

With the 26, both brands should be ok.
one caveat: the 26 is not easy to heat; some folks escape the low voltage/high current/high noise problem by using a lead acid battery for heating.
