I've owned 2 FJ40s, a Cummins swapped FJ60, driven many 2F powered FJ60s and 3FE powered 62s, owned an FZJ80, owned and daily drove a HZJ73 and now I own and daily drive a sweet BJ74.
Some have mentioned it above, but the 70 series is really the spiritual successor of the 40 series, which is my first love. I have zero issues recommending one as a daily driver, just have it well sorted and don't expect to set any land speed records. I would say build quality is a notch higher than what we saw with the 60 series, and you can get a nice one with AC and power windows with enough comfort factor to be used daily, but it'll still remind you that you're driving a truck. Some complain about the suspension, but your average OME medium suspension kit will solve those issues. I'm currently on 33s and have zero issues stopping (my HZJ73 was on 32s and felt very similar), it behaves much like a 60 series. I also require a manual transmission, personal preference, I don't mind a stick in traffic, especially in a low geared 4x4 that will lug around during rush hour. I will say an automatic absolutely kills the fun factor, I've driven an automatic HZJ73 and it just isn't quite the same drivability wise. I think a 1HZ is one of the best truck engines ever put in a vehicle. A 5 speed HZJ73 isn't fast, but it's fast enough, it's smooth and returns good fuel economy. My 13BT powered rig is fun and rowdy, and I have factory cable lockers and a manual as consolation prizes, but I really do miss the 1HZ.
One of the reasons I went down the diesel road is that I got tired of horrendous fuel economy. I currently get fuel economy in the low to mid 20s, and I got low 20s with my HZJ73 consistently. That extra 7-10mpg makes a HUGE difference, both on the wallet (even with high fuel prices here in sunny CA) and it really makes planning long distance trips much easier without having to make all of those fuel stops. You'll finish trail rides with 3/4 of a tank, not having to watch the fuel gauge and wondering if your buddy has enough fuel in his jerry can to spare a gallon or two if you find yourself running on fumes.
