I have several friends with Frontiers, I have a 2007 Tacoma 4 door. I looked at Frontier and at the time the back seat on the Toyota had a lot more room. Not sure today. As near as I can tell the Nissan might well be just as good. It just doesn't have the reputation, or the resale value. Long term, and with resale value figured in it will cost about the same to own both.
I only know one person driving a Titan. A local deputy who is a bloodhound dog handler drives a 4 door 4X4 Titan that belongs to the Sheriff's office. He has been pleased with it. It has performed well off-road, even had to use the winch a few times during searches so it isn't babied. He often pulls a pretty heavy trailer too. Gas milege is pretty bad, but he ain't paying for it. I understand the newer Tundras are just as bad.
