The Panasonic drivers were 125 MHz devices, i can imagine Mr P. choosing such fast devices with good reason.
The drivers and center complementary set of output devices work as a precision output stage at low level signals.
The additional rows of A6 and A8 devices tag in at higher output levels. The number of such slow devices in parallel make them perform quite well at high output power, the magic is in their total number. Given the shear number of output devices i can not imagine it makes much difference if you go for MJ15003/4, MJ15024/25 or higher Hfe types like MJ2119*s. I'd say: go for the ones that are the cheapest.
It's like an Alaskan sled race, 12 dogs pulling the sled but you need the very best ones in front.
The Master will have to say if you can use the MJE15030/1
