Get one that fits.
Most comfort issues arrive with a bike that is the wrong size. Too large and you will be stretched out and too small and you are cramped. Even when the right size-it may still have fit problems with saddle and bar position.
Then as some of us have found out- there is component sizing and quality of parts fitted.
Comfort on a bike is not an art- it either happens or it doesn't. Saying that I ride road bikes and each one is set up for me. Frame size is right and they are set up for me but each bike has its own quirks. one of the bikes is about to get a bar change to "Compact" bars as after all those years- I have decided that the standard size bars don't fit me correctly. It has been fine for 6 years but it suddenly feals wrong and that is my distance bike.
So down to the LBS-----and find that first---- and see what they have to offer you.
