It sometimes takes practise
I did not sleep very well first nights (it actually took about 7 nights), it feels so unnatural to sleep while hanging. It sometimes still does.
But when one compares hammock sleeping to tent sleeping it is always great to wake up without ache in back, neck, hips and shoulders. And usually hammock is dryer than tent also. And there is more room under hammock tarp than normal tarp or tent, more room for camp activities also. Usually one can do almost everything while hanging in hammock.
The difference to tent sleeping and camp activities was my main motivation to learn how to sleep in hammock.
My first hammock was a simple cheap TickeToTheMoon. After I got that I needed bottom insulation I did order Hennessy. And after I noticed that side opening is better I bought BB. When sleeping in BB was so comfortable I tested the TicketToTheMoon again and was greatly surprised that it was almost more comfortable than BB. This cycle took about 2 years. So probably Your problem is not price or model of the hammock you just need more practice.
