I'm a fan of bigger is better for hauling, so if you can stretch it a bit, go for the tundra.
When I was looking, considered the tacoma, but tundra has a weight/power advantage, plus more comfortable cabin.
Has to do with seat height above floor, distance to petals etc. (I'm 6 foot, 200 lb) but just didn't fit into the tacoma comfortably.
6 years on my '07 tundra trd, quad door, still love it.
That said you can't go wrong with either the tacoma or tundra.
Second tip - take a look in the states - when I bought the landed cost of the tundra was about the same as the locals wanted for a tacoma, even with a $0.92 dollar.
Importing not that difficult, search for some of the older threads.
