Mate...I bought a Oztrail Biker Swag a couple of years ago....Spent one night in it and I found it was a PITA. (Ended up giving it to my son).
The supplied mattress is just a bit of 50mm foam....It is bulky/heavy and next to useless comfort wise.
The only thing in a swags favour is they are relatively quick and easy to set up..It is all downhill from there.....They are cramped and difficult to get in a and out of...not to mention there is nowhere to stow any of your gear
I guess it all depends on what you intend doing. If you hanker to do multi day rides, and camp most nights I would recommend a tent and a good inflatable mattress (Exped).
My preferred tent for multi day rides is a Mannagum "Howqua" 2 man hiking tent. A quality unit at a reasonable price...especially when Wild earth have them on sale (Regularly).

Plenty of room for me and
all my gear. Very easy to set up and take down. Packs down small
