I think Baker's 80 might be a bit of a stretch, but your point is taken; it's a valid one.
As I've posted before, I think it boils down to personalities, particularly between DM and diver, and diving styles. Does either the DM or diver like swim-throughs? Like to go deep? Like to fly? Like to find the tiniest critters? Is quiet during the si? is a boisterous goof-ball? And on, and on, and on.
True. A good DM/diver fit can make a big difference. Same with the shop's personality. "Good fits" there and a diver will climb mountains to dive with that shop/DM. Unfortunately, it would be very hard to match DM/shops with Scubaboard posters asking for a shop recommendation based on personalities. Logistics, on the other hand, do provide a way to narrow down the choices.
This is why I don't bounce up and down and say "DEEP BLUE or SCUBA SHACK" every time someone wants a dive op recommendation. If you called up Scuba Shack and said you're staying downtown and want to dive with them, they'd make it work, somehow, just like Blue Magic or Tres Pelicanos would. I happen to know that Deep Blue leaves from downtown and could pick these divers up on the dock at Hotel Coz or "near Scubaclub". As Scuba Shack was/is more than one dive op, they may be able to do the same, but as far as I know, the divers would have to get down to the Scuba Shack shop by Park Royal. As fine a shop as they are, I wouldn't recommend Scuba Shack to these divers, just because I like the Scuba Shack folks and their dive program. Logistically, there are better shop options.
I've stayed at Casa del Mar almost exclusively. The hotel is considered kind of a "divers hotel". They start serving breakfast at 7am. Trip after trip, I watch all these divers who dive with different ops (CDM doesn't charge a dock fee) wolf down their rushed breakfasts so they can get on their boat. Madness, imo. I'm on a dive vacation and would rather put my energy into diving 4 dives a day. At 10 minutes to 8 I'm still sipping coffee and looking forward to the dives. When I'm good and ready, I take a very short, leisurely stroll back to my room and get my cameras and wetsuits, etc, together. I take my time. I'm relaxed. I have until sometime after 9am until the Deep Blue boat picks me up at the dock. Long ago, I stayed at CDM and was diving with one of the "top ten" shops. The owner would pick me up on the street to get me to the caleta. Good enough shop, pleasant people, excellent boat, great DM, but it was a PITA. I'd rather spend my time whizzing down the coast in a boat with plenty of room than sitting in a cramped vehicle, having to lug my stuff around. Same applies if I were staying downtown, which I've done. YMMV.
But yeah, lol, Baker's 80ish is a little stretch.
