I really don't have any vested interest to sell anyone on not doing a liveaboard, however, in my expierence the central islands provided an expierence that, at a minimum, equaled my liveaboard expierence to Darwin and Wolf. Conditions can always change and there are no guartentees, but my expierences at Darwin/Wolf were disapointing. No whale sharks, plenty of individual sharks but no massive schools. I will say Fernandina was the highlight of my liveaboard expierence, with a flora/fauna assemblage very different than the rest of the islands.
The OP's question was whether its worth it to consider a "dive vacation" in Galapagos without doing a liveaboard and I couldn't agree more. The best dives I've done in Galapagos have been at Tortuga (schooling hammerheads, orcas, mantas) and Leon Dormido (baitball), both day trips. Additionally I've had incredble freediving expierences at Seymour Norte (many mantas and hundreds of rays), Floreania, and Punto Moreno (whale sharks, Bryde's whale, cormorants, mobular rays).
Unfortunately with park guidelines how they are, there is no one way to easily see everything the archipelego has to offer. My reccomendation to anyone with the time (and money) who really wants to be satisfied with seeing everything Galapagos has to offer is to do a dive liveaboard (Darwin, Wolf, Fernandina, and northern Isabela), a land tour liveaboard (dive liveaboards aren't permitted and don't have the time to do many land tours in more remote/scattered islands), and then an additional ~2 weeks between Isabela, Santa Cruz, San Cristobol and Floreania staying in hotels/hostels and enjoying tours based from local ports.
