Honestly I don't think there is a comparison.
It's really like Apples to Apple Sauce comparison. Kinda the same component but used in two completly different ways.
I would not pay what I pay for Disney Hotels IRL.
For what I pay for a value, I could get a hotel room anywhere else with decent fridge/micro or even a kitchenette and for sure it would have a coffee pot, bigger rooms with enclosed bathrooms (though I will tell you I am one of the few who actually do prefer the sink out of the restroom because with multiple people it's easier to get ready), and a free breakfast.
Same at Mod and Deluxe level. In the real world that much money would get a whole nother level of service and amenitites.
It is better now that at least ALL the rooms have a fridge and internet but still. Offsite I"d expect more.
However to be Onsite and use the buses, with pretty easy access to your room if you need a break or to an activity if you decide last minute to hit a park for an hour, and be "in the bubble" so to speak, I'm okay with the value/mod price. Deluxe I'm a little more doubtful. I'd only stay deluxe again with a really good discount, just because for the up price I don't use enough of the deluxe perks to make it more reasonable than a Mod.
In the real world I do two kinds of stays. I do what I would consider 4 star stays in Vegas and various gambling resorts, plus some other resort stays in various vacation spots. Think Marriot/Hyatt/Hilton types plus a few private owned like Moody on Galveston Island types). No Disney Deluxe hit the same services at the price that I can get offsite.
I also travel for guick weekend getaways and kids sports tournements which are mostly at the 2 or 3 star level (Holiday Inn, LaQuinta, Hampton, etc), which offers services that at Disney you can only get at Deluxe level or by paying hundreds of dollars for Club access.
I refuse Days/Comfort Inns, Motel 6, Super 8 types if given any choice. Hate that level of basicness off site and low prices are not worth it. I don't think anything on Disney Property is as bad as a Comfort Inn or Motel 6 but in truth Values are very basic and offer very little in the way of perks other than being 'onsite at Disney'.
I think I get more bag for my buck at Hampton then Disney, but most Hamptons don't come with Mickey Mouse and themeparks.
Onsite I've stayed all three levels and am fine with them (I mostly do Mod/Value). Off site I would probably never stay anywhere that was not at least what Disney calls a MOD.
