Sweden,Visit Visa Or Tourist?

Mrs asked me which is best for her friend/salon customer,

Friend has found what seems like a nice fella in Sweden, now, there only contact has been through e-mails, for about 3 months, is this a setback when applying for a visa, therefore would a tourist visa be better than a visit visa [whatever the difference is?]

This young lady has a young child and works for the goverment, she has the money to pay for her trip if need be, but as i understand it, she has asked him for a 50/50 airfare split,

Ive tried the visa history search, but didnt come across thiss particular question, as i read the posts there, it seems a lot easier than getting my mrs to UK on a family visit visa,

Thanks for any help, Lickey.
