I had a 2011 Tacoma Double Cab TRD Sport 4x4 for about a year before I traded it in for my F150. I really liked driving the truck, and think it was a great size for a truck if you're not towing something very big. It felt way less "boaty" and more controlled on the road than my F150 does.
Besides towing performance with a TT (16 foot) and poor MPG for the power you get, my main gripe was that I didn't feel it was great value for money. I had about the most loaded Tacoma you could buy that year, and it lacked tons of nice-to-have things that my F150 has, for not much less money. Prime among my complaints was the inability to have heated mirrors (had to wipe the dew off every morning), no leather or heated seat options, no sunroof available, etc. I also had a few issues with mine, with the HVAC blower needing to be replaced at 7k miles due to squeaking bearings (common issue I think) and also had a rattly windshield clip under the headliner.
If they were available for 25% less than a similarly optioned F150/Silverado/1500 RAM, I think they'd be great. But they are so close in price (even moreso used) that unless size or sporty handling are a priority for you, you might get more for your money with a full size.
