I don't know which one is BEST, but I first recommend that you calculate the amount of BTUs of cooling you will need based on the space you are cooling. If I recall, that number was somewhere in the range of 6000 judging by the square footage of my apartment.

The next thing to consider is if you are going single hose, or dual hose. If you are operating a single hose unit, it is drawing air out of the room to dissipate the heat outside. This also means that it will create a vacuum that will draw air into the room, and into the nearby rooms.
With a dual-hose on the other hand, the condenser is cooled with outside air, leaving the pressure of the space unaffected.
Though dual hose units are more expensive, they are worth the extra $$. My Garrison single-hose unit struggled with anything above +30, the dual hose Wynter unit cools a larger space easily.
Also worth taking into consideration . . . self-evaporating or not. Almost forgot about this part.
The Garrison I had drained through a hose into a pail. Depending on the humidity level, that pail could fill up mighty fast, or sometimes hardly any in 8 hours.
The new unit, however, self-evaporates the condensation into the outflowing air. Though it apparently can cut out if it can't keep up (requiring draining), it has not happened with mine yet.
