I faced the same Trainman, and without seeing both sets of liners in the same vehicle it's kind of tough to compare. Both companies claim that the mats are custom-fit for each vehicle, and realistically I'm sure they both fit fine and are very high quality.
I've been very happy with the Husky mats. The fit in the Forester is great, and they seem very durable (no warping/cracking or anything, but it's only been 8 months). The plastic on the Husky liners doesn't appear as "premium" as the WeatherTechs, but the reasons I chose them over the WeatherTechs are:
A) Slightly more coverage overall. They go up a little higher on the sides, and have much more coverage over the dead pedal. Also, the fuel release latch is covered too (though there's a section on the liner that can be cut out if you want free access to it). I really like that it is covered, as my other vehicles always seemed to get a bunch of debris down there that is impossible to vacuum out. BUT: it means lifting the liner to access the fuel release latch - and watch out, those teeth on the bottom of the Husky liner are sharp! (which keeps the liner firmly planted to the carpet).
B) The Husky liners were about $10 or 15% cheaper than the WeatherTechs for front/rear. Likely depends on where you order from, and if anything is on sale at the time.
Can't go wrong either way I'm sure.
