Sadly this isn't a one answer question. Many people have different saddles they prefer .
My first suggestion would be to get your sit bones measured. You definitely don't want to do a long ride on too narrow of a saddle. Most bike shops should be able to measure for you. From there, many shops also have loaner saddles that you can try out for a bit.
I currently ride a cheap EC90 saddle that I found on eBay for $20. It's 155mm wide and seems to replicate a Specialized Power saddle. For $20 it was worth trying out before committing to a proper $130 saddle.
