If that Shiloh is a B serial number, you'ld best jump on it if possible, chances are you could double your money in a week on gunbroker. If there is no B in the serial number then it's still a good buy , providing the thing hasn't been abused.
When it comes to Sharps v Handi, I'll only say this, at the Quigley and other such "buffalo" matches I can think of not one time did a Handi finish in the top ten, and I'ld be really surprised if any ever finished in the top 30%.
Just depends on what you want/expect out of your rifle, short range blast the target the handi will do it all day long,stretch the range out past 200 yds and the Handi will get left in the dust.
