rhill is absolutely correct. Difficulty is very different from time consuming.
The "easiest loading" I have ever done in 45 yrs of loading bikes is with the "WheelDock". It is ridiculously easy, safe, and incredibly fast - BUT you still have to use at least "some" straps. It is far more elegant than a Baxley or a Condor wheel dock, and is way "easier" than a TRS.
Most of the time I'll get the bike close enough to "force" the lock-in with the TRS on the first try, but it takes more thought and effort. On the other hand, I've gotten better over time, and once it's locked in, you're done. And the final solution is far more secure IMHO.
It is all at least to some extent personal preference - with the exception that it is not just opinion that the TRS is better for your suspension - that part is not really open to argument IMHO. The other disadvantage of the TRS is that it's completely bike specific, where as other options are more flexible. One model of the "WheelDock" will work with virtually any sport bike. A Condor for example is even more flexible. Everyone has to make their own decisions.
