Congratulations!!
I personally have driven nothing but Nissan's until my Genesis Coupe and drive a 2015 Rogue now and love it. All my Nissan's in the past were ultra reliable with minimal maintenance costs. None of them ever left me stranded.
Nissan used to make decent cars after their first fiasco but Nissan's quality has gone down again leaves a lot to be desired in terms of quality and reliability and they are not doing so well.
Nissan was always two notches below Toyota and Honda in terms of quality and reliability.
You pull up any list for reliability and Customer satisfaction, Toyota and Honda tops the charts.
Nissan... never been there and not quite there yet if ever.
Infiniti used to make decent cars in that segment especially G35/G37 but Infiniti seems to have mucho problemo offsite with their sales and vehicles so much so that they have discontinued their best selling car, the G35/G37
Lexus is the undisputed king of that segment . Acura was ok for a while with their TSX & TL but ever since they morphed them into TLX and put in a 8 speed transmission with DCT, they seem to have lot of transmission/shifting issues. RLX is a pretty aged sedan. I do think given Honda's track record, they will get their act together at some point. Nissan is a long shot.
If you look at their bread and butter divisions, both Honda and Toyota models will eat the Nissans for lunch. Nissan quite doesn't have it.
Sorry dude, but Nissans are second rung cars compared to Toyota and Honda

On the luxury segment, the Lexus line blows away the competition. Neither Acura nor Infiniti comes anywhere close to Lexus.
Actually Nissan has even more tighter competition now with Mazda kicking ass with their 3 & 6 and I am quite impressed what Mazda has done with their 3 & 6 models.
