"which are the best of the best of toy haulers"
That's really more personal opionion than any fact. Every rig out there has some flaws. Researching the various units will show you what features you want/need and how much you are willing to pay for them.
"fifth wheel is safer than a trailer"
Generally I'd agree, but a TT can be setup very safe as well with the right hitch. I've prefered my 5er towing vs. my TT's. Safer? I guess, it just tows better and I haven't had sway issues at all.
"should I just get a motorhome toy hauler"
Depends on your personal needs and budget.
"starcraft travel star sport-utility trailer"
If that works for you go for it, I've done the PopUp & Hybrid trailers - prefer a hardsided trailer so we can camp year round and have less setup time.
