Wow. Kaiser HMO here. Their emphasis is preventive medical care to reduce the need for treatment, and they're pretty good at it.
None of those pharmacy hassles. Walk downstairs from clinic to pharmacy and they are already preparing your order, your name appears on a message board in a few minutes. Pay $5~$10 deductible sometimes, and walk out. It's rare to be asked to pay retail for a prescription and their generic Iboprufin, allergy medicine, etc that is non prescription is inexpensive. Mailorder similar. Everything (in our experience) gets mailed out by their regional pharmacy by next day. What you pay to subscribe, covers all the BS so you never see an invoice.
Health care treatment likewise, usually a $10 fee as you check in for anything then never an invoice or discussion of cost.
Going into Kaiser can feel like the DMV but that's just the screening counter, the medical professionals are excellent.
I hope it isn't too political to say Kaiser has been looked at as a model for lower cost health care.
