I have never tried a sex doll but I can give you some pros and cons of prostitutes.
Pros:

She will have sex with you

Usually complete sluts

Allows you to practice intimate contact

Lowers inhib

Removes fear of foids, sex and rejection
Cons:

She wants your money

She wants all of your money

She wants all the money of the guy sitting next to you too

She knows the truth about hypergamy and incels and makes a living exploiting this knowledge

She will fuck Chad for free

Will always frame herself as victim

Much more accustomed to fakery and deception than normies

The exciting part for her is to see how much she can gain. Money, gifts, drinks ECT.

She will want to make it quick so she can move on to the next customer

STDs

If you fall for a prostitute and she plays along you will end up supporting her, her bastard children, her parents and her friends alcohol addiction

Cucking is her lifestyle
