Pino is an excellent musician and tastefully bopping bassplayer, but he doesn't know what rock is even if you hit him with one. His bass playing with The Who is as out of context as if Bob Marley had replaced Ritchie Blackmore with Deep Purple. That is the big dif to JAE who was nothing but a rock player, albeit a busy and original one, but he played anything with a rock edge. The Who could have found bass players galore with a rock feel, but chose not to. JAE once said in Kenny Jones days that he misses Keith Moon "as a person, but not as a drummer, my job has become easier with Kenny drumming". I'm not sure whether JAE did not misjudge the musical chemistry he had with Moon in that quote, but it seems that Roger and Pete feel the same about JAE, they don't care for that type of bass playing. And it is not like they don't try to recreate other historic components of their music painstakingly, just listen to the intros of Barbara O'Riley and Won't Get Fooled Again, they practically ape the old synth sounds on those.
