No one was ever obsessed with chess as much as Bobby Fischer. Not Magnus or even Morphy.
Paul Morphy vs Bobby Fischer: Who would win?

if morphy lived in our time he'd definitely be stronger than a lot of people. considering his day and age though, he's easily worse than bobby

i think with unlimited games b/w morphy or any modern player will be morphy will get defeated in starting games then he will improves then he be able to atleast make some draws .. then after some more games he will be able to win one games here and there then after some more games he will win like 50 percentage of time then after some more games his win percentage games wil increase then if morphy dos not lose interest in playing he will win major percentage of games.
in short he was an adaptive p player a genius much more talent ed player then fischer in his own words if u read what fisher has to say about morphy.
the way he could give different kind of odds in chess and still win shows he games learinng were unique to him not copied from any books computers.
but in the end i will say he was not unbeatable though people say many games he lost to chess to his opponent to give them a boost and cheer them. his thought level in playing was to that level he can lose when he felt that the other person needs win more then him.
he was complete gentlemen.
Fischer would win
